Hi all,

I'm intending to retube my ampeg svt classic (reissue) with either
sovtek 6550we's or the electro harmonix 6550's. They're both priced
about the same, which would be the better choice? Thanks.

Put some real tubes in that prick,, Don't listen to the Turd Mongers,, the
only tube for that amp is the GE 6550A,, Jim McShane has a fine stash.

In ADVANCE

**** THE POLISHED TURD
Yup,, that's you FAT WILLIE

I also have a fine stash of NOS GE 6550A. Excellent tube.

Sometimes, however, folks are short on cash and can't
spring for NOS. The Sovtek 6550WE is a good choice;
in fact, there are people who prefer the tone of the Sovtek
over the GE. (Horrors!) One of those people is Tod Smallie,
bassist for the DTB (and the Yonrico Scott Band, which just
released their first CD) who is now going on three years
of 200+ dates per year with the same set of Sovtek 6550WE
I installed when I rebuilt/tweaked his 1973 SVT head (and sold
it to him).

It's all a matter of taste. Mine, in fact, runs to the Tung-Sol;
as far as I'm concerned, in my bi-amped 122 Leslies there
is Tung-Sol and then there's everything else. No tellin'
what folks might like.

Have a nice day, son.

What period do your GE 6550's date from? Are they all stamped Rivera?
Were they assembled in the USA?

I am amazed at how old those amps get before I see them needing tubes. Those
ancient Tung-Sol kick ass. I haven't seen NOS on them, is there any supply these

Ron, I think I have some pictures of and SVT that stop in the shop about 2 years ago that
had a set of old Tungsols STILL running. Still did the full monte.

The getter flash had turned gray years ago, and there was still no reason to pull them.

It's very interesting how the name Ed Jahns is associated with both the Tungsol and
Ge-6550. And, both tubes tubes had HIS 400-PS design bring out the best from them too!!!

A most amazing man of the times!!!!!

I'm just most thankful to have worked with and learned so much from the man!!!!

It was not uncommon for a set of GE-6550A's to last over five years of heavy full time
professional use during the Magnavox years of SVT.

The best tubes ever made for an SVT or 400-PS.

You are fortunate: the 6550 is a very rugged tube and any brand that
is not poorly made in China etc. is about equally good, it's a hard
tube to screw up & still meet spec. Take LV's suggestion, ignore the
snobs & try the Sovteks from him, you'll be happy and not broke.

Snob?

SNOB!!!

This sonofabitch calls US a snob!!!

YOURE GODDAMN RIGHT!

Take those turds and put em in the friggin TERLET where they belong!! :-)
LOL

Just felt the need to poke a stick into the cage of the Turd Mongers.

To paraphrase an old saying, "One man's turd is another man's treasure."

It's all so subjective. Haven't you ever met a guitarist who treasured
nasty old 12AX7's with gain out the bottom and just the barest breath of
emission, because they sound so (choose your description) cool and
crunchy -- ballsy -- just like hendrix, man.

EXCUSE ME!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!


Are you in some way trying to say service life, and sustained high performance level IS,
or is NOT reflected in that cheaper price!!!!!!

The 6550WE in a Twin Reverb is one thing!!!!

In an SVT or 400-PS, it is totally an other world.

The 6550WE is NO GE-6550A. It's not even close!!!!!!!!

Sonically, or electrically.

For the bass player who has that, I'm going to push this amp till it blows attitude, where
the amp has to fill the club, the GE-6550A is the only tube to use.

BUT, if you are one of those bass players who plays before that threshold, and have a DI
and mic on the speaker cab, feeding a concert level house sound system, 6550WE's work ok.

It depends on if the bass player shakes the house with HIS Bass amp, or the sound system
shakes the house for him from the DI, then his amp really becomes HIS bass stage
monitor,...

which tube is better for the application!!!!!!!!!

Mind you, you have my utmost respect, but I think you're being a
bit of a zealot here. Ferinstance, when I push the (also very
expensive) 7581As for old Fender 6L6 setups, they're different
and you can tell, but it'd be a helluva stretch to say "not even
close".

Fer me anyway, sonically and _electrically_ not even close for a
6550 (but still keeping among power tubes) would be an EL84.
Maybe an EL34?

Don't NEED to. Any one standing in the room listening to the sound of the bass coming off
the stage will tell you the difference. Just put them up there side by side.

Not to mention the test bench tells the story.

With a stock 400-PS, I have to mod the damn thing to keep it from smoking the
6650-WE's!!!!

And, after that is done, they can't even get the output of the 400-PS to stock rated 435
watts output on the three loads required!!!!!!!

Then, after used in for a few months of gig playing on it as a hard ass POWER PLAYER, put
it back on the bench, and see where things sit on the test loads again.

BTW, that spec is 435 watts R.M.S. at *50* Hz. Clean sine wave before clip!!!

That sine wave looks a little squirrelly down there with those WE's.

What does an SVT do at that 50 Hz with 6550-WE's after the same
treatment!!!!!!!!!!!!!!!!!!!!!


Mind you, you have my utmost respect, but I think you're being a
bit of a zealot here.

No, I'm none of that.

I'll tell you what I am though.

I'm a kick your ass bass player ALL my life. There is nothing timid of shy when it comes
to my bass providing the horsepower in the songs to ROCK the HOUSE, when I'm on stage in a
formal band!!!!!!!!!!!!!!!!!

I played the Big amps and the Stacks, when they were in fashion. And, the SS crap bass
players use today, with that freaking in your face EQ'd sound, is NOT my idea of what bass
is all about!!!!

I'm old school, and not about to change any time soon!!!!!!!

Big fat gut bottom that rumbles through the club's walls into the parking lot, without
getting in the way of the band in the house, is what I'm all about.

But, that is not what today's bass player is all about, with his in your face bass rig
that falls on it face when I hit my neck pickup on my 66 bass, and the amp hits clip
trying to get down below the low end roll off.

That place below the roll off, IS where the freaking BASS belongs in the MUSIC.

Even Willie knows what FAT BOTTOM from a B3 is all about.

Ask him if He'd like to slap a 10" power piston in a 122, and not find the low end
fundamental rolling around the room on the floor soft as a pillow. But NOW, it's IN YOUR
FACE, where you HEAR it, and DON'T *FEEL* IT!!!!

400-PS amps present the bass like I like it. And, it takes TWO, not one, but TWO killer
setup SVT's with GE's and FOUR 8x10" cabs to equal tricked up 400-PS.

And THAT, is FACT. Rich gray's band opened for Black Oak Arkansas using one of my tricked
up 400's and four custom cabs. Black Oak had the Ampeg endorsement, and the bass player
had the SVT's.

But, after the first show, their bass player comes up to Richie, and asks if he could use
the 400-PS for the rest of the tour. I know its fact, because Richie called me for my
opinion. I said, let him do it. What the hell, have fun.

Later, that same 400-PS got people sick in the Filmore East from the low end of an ARP
synth.

If there is one thing I know, and have experienced, is the power of the Big Bass Tube
Rigs.

I've lived it, when most you guys were either doing something else, or weren't on the
planet then.

I had my vision blurred standing in from of a dual SVT stack playing Sunshine of your
love, when the record broke. BTW, that's two SVT heads, and four 8x10 cabs.

So, till you been there and done it, what are you going to tell me about it!!!!!!!!

I can't wait for things to come together where Kent and I can have some fun doing a stack
gig, doing it ALL exactly the way Jimi did it, so some of you all can *EXPERIENCE* the
Experience, as people did when a lot of you all MISSED it!!!!!!!!!!!!!!!!!!!!


Ferinstance, when I push the (also very
expensive) 7581As for old Fender 6L6 setups, they're different
and you can tell, but it'd be a helluva stretch to say "not even
close".

I ain't talking 6L6's, you are.

When it comes to 6L6's, My purple monster blows away 900's and 2000's in front of their
owners, when comparisons are done.

Then, you should SEE the look on their faces, when I pull the purple monster stack away
from the wall and turn it around, and all they SEE sitting the sockets are a PAIR of OLD
GE-6L6GC's!!!!!!!!

Yeah, NO ****!!!!!!!!!!!!!!!!!!!!!

Now, that is no brag, fantasy, or drugs talking.

It's just MY reality!!!!!!!!!!!!!

And, anyone is free to stop in the shop, step into my reality, and EXPERIENCE It, for
themselves!!!!!!!

Look, I've heard people talking their ****, and it comes off like they are on the same
page as I am.

BUT, when you are in the room with me and my gear, it's a whole different
world!!!!!!!!!!!!!!!!!!!!

And then, you will know, I'm in whole different place that really exists, where the music
becomes a whole different kind of spirit, which moves people, because they can *feel* it.

Yeah, the clubs are smaller, and the sound man tells ya to TURN IT DOWN, for that 5000
watt house system.

Yeah, you weak back guys want your air boxes with all that gain, so you can get a piece of
what I'm talking about. But that's all you're EVER going to get. Is just a freaking
SMALL piece.

You ain't going to FEEL it. Or what it FEELS like to SMOKE the SET, and SMOKE the crowd,
as the Music Takes You, and THEM Higher!!!!

Those are not just lyrics to a song, they're REAL!!!!!

The MUSIC, alone, really DID, take YOU, HIGHER!!!!!!

Not like today's music tries to, with the sound of PROCESSED Guitar sounds.

THAT'S, freaking Bull ****!!!!!!!!!!!!!!!!!!!!!!!!


Fer me anyway, sonically and _electrically_ not even close for a
6550 (but still keeping among power tubes) would be an EL84.
Maybe an EL34?

That's so small a piece, you can't even get an idea of what I've experienced on the stage
from the music.

Most importantly, there ain't enough in the written or performed MUSIC, to take even a
garden slug higher with that on the stage, for today's reality.

After thought

There is one man *out there* more than me.

Bootsy uses 15 KW Crown power on stage when he plays. No Less!!!!!!!!!!!!!!!!

How do I know this,...... look.

http://timeelect.com/Book22.htm

There you go.

GE-6550A's, ain't got no equal with the numbers 6550 on the glass!!!!

The 400-PS, is the test bed for that ****!!!!

It was designed for it!!!!!

watt house system.

Yeah, you weak back guys want your air boxes with all that gain, so you can get a piece of
what I'm talking about. But that's all you're EVER going to get. Is just a freaking
SMALL piece.

You ain't going to FEEL it. Or what it FEELS like to SMOKE the SET, and SMOKE the crowd,
as the Music Takes You, and THEM Higher!!!!

Those are not just lyrics to a song, they're REAL!!!!!

The MUSIC, alone, really DID, take YOU, HIGHER!!!!!!

Not like today's music tries to, with the sound of PROCESSED Guitar sounds.

THAT'S, freaking Bull ****!!!!!!!!!!!!!!!!!!!!!!!!

Fer me anyway, sonically and _electrically_ not even close for a
6550 (but still keeping among power tubes) would be an EL84.
Maybe an EL34?

That's so small a piece, you can't even get an idea of what I've experienced on the stage
from the music.

Most importantly, there ain't enough in the written or performed MUSIC, to take even a
garden slug higher with that on the stage, for today's reality.

After thought

There is one man *out there* more than me.

Bootsy uses 15 KW Crown power on stage when he plays. No Less!!!!!!!!!!!!!!!!

How do I know this,...... look.

It is with interest I read your ideas about providing music
with feeling, rather than with false edgy sounding fake bass.

I also see the Fender 400 watt amp you refer to has only 6 x 6550
tubes to make the 400 watts, which means 133 watts per pair of 6550,
which is rather a lot of stress on the tubes, regardless of the brand of tubes used.
When such an amp is is pushed into over drive one would think
that screen currents and grid currents could be rather high,
and the danger of tube damage would be ever present,
especially if someone connects too many speakers accidentally.

Ever thought of using a dozen 6550 to do the job?
This reduces the power per pair to a more survivable 66 watt.
Audio Research use 16 x 6550 for their Reference 600,
and that 75 watts per pair, same as a humble McIntosh.

See http://www.turneraudio.com.au/htmlwe...00monobloc.htm
to see a sample.

My amps make about 200 watts of class A, and its all very relaxed
and the idea is to have limitless headroom for a hifi situation,
where effortless and distortion free sound is sought.

In one of my 8585 hifi amps, I used 8 x jan GE6550, nos, green lettering.
They were about twice the price I pay now for EH6550.
I don't know wherther there was anything really special about them.
After 7 years of on -off use in a hifi situation, they all became prone to
grid current even at idle, and some of the grids going a volt or two positive.
Then I reduced the bias resistors to 100k, and they held their bias better.


The client had me replace all the tubes with EH 6550,
and he said there was a big improvement in the soundstage,
which seemed to have depth, not only width, as before with GE,
then he said the dynamics and detail were improved.

Hifi amps are never subject to severe signal overloads and gross clipping
with rock musician amps.
But they are left running for hours on end, day after day,
with a substantial bias current to allow lots of class A.
I guess the tubes wear out for different reasons in the
music amp versus the hi-fi amp.

One of the sweetest music amps I heard was 6V6 PP,
about 80% UL taps, nearly triode, in class A.
Another 6V6 in triode drove the output stage via a transformer.
This amp was one of the few which seemed to have sweetness
and a sort of natural reverb, but without a reverb unit used.
The owner-builder was a physics lecturer, whose interest off campus was guitar,
and rocket engines.

Another client uses Sovtek 6550 in triode in a Marshall head for use
in his "dark metal" band, and the sound is basically like a continual stream
of jumbo jets crashing on the pavement in front of you.
Not my cuppa tea, but some folks think its very cool!
The tubes are either off, or 40 dB over clipping.
After 4 years, I think he's on his second pair......
The first pair expired after using too low a load impedance
when swithed to the 16 ohm setting.
So when I hear about tubes failing, I wonder first
about the human element.

Unlike Fender, I fit individual cathode current sensors
to each output tube so that if any one tube out of so many
misbehaves, and goes red with too much cathode current,
the amp is turned off.
That mightn't suit a muso, who might prefer to blow a few tubes rather than stop
to change to a spare amp between songs, if the fuse hasn't blown.

EL84 in a Vox AC30 sound sweet as, and smooth tubey over drive,

In some other amp with higher B+, and lower idle current
for near class B, they ain't so good.

I some how think it ain't what you got that is everything,

Yes, how it is set up makes a huge difference, no a Vox AC-30
isn't really class A.

My point was (and continues to be) that Rich is describing
GE6550s vs Sovs as if they came from a different planet. I'm
guessing further (though Rich hasn't explicitly said so) that
he'd classify the Sovs as polished turds. I'm merely suggesting
that, while for Rich there's no other tube than the GE and no
other amp than the PS400, the OP is looking to retube a reissue
SVT and the OP may be quite satisfied with the Sovs (at half
the price no less). And it is the OP's needs we're trying to
address here, right?

The 6L6 comparison wasn't meant as a comparison of 6L6 vs 6550,
but to serve as an example of gradation between similar tubes.
Remember, Rich claims that the GE and Sov "aren't even close"
sonically or electrically. Maybe so in his tweaked 400PS and to
his ears and playing style; there may not be as strong a case
in the OP's RI-SVT and to the OP's ears and style.

Yes we know the amp.

Electrically, it would be a stretch to make a distinction; unless the

would seem to be a rash statement unless some mfgr's version sucketh
in specific, doccumented ways.

But it was/is not uncommon for some to run them above their 35w plate
dis at full power, which our old GE's sometimes tolerate somewhat (and
sometimes didn't or won't, as well).

None of us hv seen it all, in my case hv yet to see a crappy 6550 that

They don't give high output yield no the loads.

At low frequency, a sine wave is not a good looking sine wave, when the GE yields one.

The screens are not as hardy as the GE's.

Their service life for high power yields is short when compared to the GE.



If so, what specific failures have you noted or had reported - i.e.
screen toasted or etc.?

You can't stick a 6550 that is from off shore into everything you can stick a GE 6550A.

You will have to make changes so you don't toast the screens.

In low demanding unit they are OK.

A Leslie amp will not hurt them.

They may live in an SVT for a long period of time, all the while the power output is
slowly going down.

The low end punch on the B and E strings of the bass is getting flabby sounding, and you
may think you have a speaker problem going on.

It's one thing for the tubes to LIVE through the task, and another to HOLD UP high
performance yield, in performing the task.

GE's, hold a high level of performance for a LONG time.

I've NEVER had an imported 6550's give the 435 watts out from a 400-PS.

I slap in a set of GE's, and it's there at 50 Hz.

What does that tell you!!!!!!!!!!!!!!!!!!!!

Simple, ain't it.



This wld be valuable to know, as well as the
conditions under which there was a failure, if available.

Look, when someone comes in with an SVT or a 400-PS in the shop, there is a reason WHY,
they own them in the first place.

Magnavox SVT's with GE's do what they do. And, the owner WANTS that at all cost!!!!!

So, I slap in a set of say WE's. I get a call a few months later from the owner, and he
says, I think there is something going on with the amp, it seems to be getting weaker.
The punch in the low end is soft now.

Like the speakers are getting loose.

I slap the thing on the bench, and the output is now lower than were we started, and the
sine wave at low freq. is not so good looking.

Slap in a set of GE's, and the smile on his face says it all!!!!!!!!!!!!!!!!!!!

So, the WE's still work!!!!!!

They don't blow up the amp!!!!!!

So, I guess you can say there is no failure, except..... they just don't live up to the
performance characteristics, and give the service life of the GE-6550A!!!!!!!!!!!!!!!

THAT, is their failure!!!!!!!!

Well, I've run GE-6550A's at way more than 35w.

More than 50w with out protest.

My standard for a yardstick IS the 400-PS. Because, the yardstick for the GE-6550A, was
the 400-PS.

That is how the history went.

So, re-writing history to favor the imports, is what is going on here!!!!!!

Hmmm...sounds reasonable. Proven results is everything. I've only
had one 400-PS on the bench.

So, re-writing history to favor the imports, is what is going on here!!!!!!

Still seems a little odd; there is other gear that runs 6550A's fairly
hot that hasn't displayed this behavior so strikingly. FWIW one which
comes to mind is a few modulators, which run them just like a 6146B.
The original 6550A is a 6146B (not plain or A) with no plate cap, and
therefore somewhat lower max plate voltage. Most tube modulator
service is comparable to hard guitar service, electrically speaking.
The 6146B was simply repackaged to be safer in consumer gear running
lower plate voltages & no RF service.

Don't wish to over-beg the question, but we'd have to admit that
running them past their design max dis (plate or screen or both), even
if some versions get away with it somewhat, is a no-no.

One might speculate whether the imports may be less internally robust
(shock/vibration criteria etc.), possibly leading to shorter effective
life in the punishing environment of a 400-PS.(?) IOW, mechanically
cheaper in ways that only show up in butt-kicking amps?

This would also seem consistent with the low-end waveform going to pot
while the rest stays reasonably happy; perhaps (SWAG) the element
spacing (and therefore capacitance & other things) could be moving or
vibrating excessively.

You'd think there would be a few mfg'r tube engineers looking in on
what goes down here, to comment or at least take interest.

Most of the older GE Beam pwr tubes seem mechanically tough. The
6L6GC's likewise seem to take remarkable punishment, especially
inverted, while I've had "black plate" RCA's and many others old &
new, not hold up as well, and some of the former with noisy elements
right out of the box.

I feel that if modern mfgr's, located anywhere, cannot make a
particular audio tube better & cheaper & more reliable than mfgr's did
40 years ago, something is hosed up, no matter what face is put on it.

I notice nobody uttered as much as a word about the (formerly Svetlana) now
Winged C 6550C How come?. We use plenty of these in repairs and lot's in
SVT's with very good results. They aren't GE's or Tung Sol's either but they
hold up well over time and sound pretty damn good. My 2c

Hi RATs!

Winked =C= 6550WC are great wired triode in my SE amp, but, that wasn't the

VTV said the 6550WC tested stronger than the KT88, or something like that. I
run mine happily at 330V and 80mA, nowhere near what manly musicians crave

Thank you to those few who provided some relevant information amongst

It has been already stated by my hand on the keyboard, the 6550-WE is no GE-6550A, and
they won't hurt the SVT.

What short of BLESSING the polished turd, do you need.

After all, your bass amp defines the kind of bass player YOU are!!!!!!!!!!!!

People judge you by the sound of your bass.

Bands decide on what bass player they want in their band, the same way.

Gig are gotten, or lost by the sound of the band.

And, YOU *ARE* a part of that.

So, *You* want the opinions on what defines YOU as a bass player, to come from the stereo
boys, who listen to there music with their Class A Limited amps, they use for the
listening pleasure of recorded music, or another bass player who's been there and done it
all his life, playing in bands on the live music stage.

You've already had the advice of two or three bass players here, who gave their best
advice to you.

Here, http://timeelect.com/Tupgrd.htm look at the SVT on the bottom of this page.

That bass rig have been all over the world for six years.

And those tubes STILL put out a SOLID 300 watts on the bench, when it came in for a six
year checkup, and the bottom end was as STILL tight as the day I put them in.... six
years ago.

What tubes went into that thing,.... GE-6550A's..

THAT's just the way it is.

Will 6550-WE's give you six years of hard touring without a glitch.

There is a reason they are so cheap, and you can afford to replace them every year.

Good luck.

I'm sure you will figure it out.

I would guess any tube whose structural elements are rigid enough to
maintain spacing and does not readily "short" when subject to
shock/vibration. This can be easily determined by energizing the amp with a
100 Watt clear light bulb in series with the line, and with all the tubes
installed, tapping on the tubes with a rubber handled screwdriver - while
observing the series line light for changes in luminance. Changes in the
light would indicate structurally unstable tube elements - meaning it is
likely the amp/tubes will short during service. Otherwise, I doubt you would
be able to discern any quality difference. The SVT is also tough to
balance - from what I recall, and can be very touchy.

I think this is a poor substitute for a speaker and an ear.

In high gain instrument amplifiers, my instrument becomes microphonic, and will brighten

Yet, this is a normal condition, and to the train ear, one can learn which microphonics
from what location, are the unwanted ones.

Variation in lamp brightness, yields limited information.

The light will brighten as current demand to the amp increases - however, a
light brightening as a result of shock induced to the tube has nothing to do
with sound. It is also doubtful that anyone can discern any differences
among tubes built within specification - even if one's ears are made of

Well, I guess because of the poor quality of the current imported tubes and imported

trust them damn imported fuses blowing out in time to protect them super audiophile audio

To a player of a 400-PS, the difference is day and night!!!

Or, did a sneaky engineer like me, sneak it in on ya, as a result of my tweaks!!!!!!

How would you know the audio reproduction accuracy, both real and imagined!!!!!

Then, if I CAN do that with just a flute, imagine what fun I could have with you with the
electronic instruments.

The lamp is only useful as a ballast, to limit line current.

It's no substitute for the human senses, and proper test gear.

I don't know why you keep bringing up human senses or what human senses you
mean when discussing a series bulb to evaluate inrush curent - unless you
are suggesting perhaps or other body part to check the current. As for
proper tests gear - what would you use? I repaired many of these items back
when 48th Street was something other than Sam Ashe, and I always used a
light bulb - and still do today.


The light will brighten as current demand to the amp increases -
however, a
light brightening as a result of shock induced to the tube has nothing
to do
with sound.

Well, I guess because of the poor quality of the current imported tubes
and imported
fuses, you would want to use the lamp in line to limit line current,
because you can't
trust them damn imported fuses blowing out in time to protect them super
audiophile audio
amplifiers. They must be real fragile too!!!!!!

Seems I recall as many GE's failing the lamp/shock screwdriver test as any.
Now I see you don't like dem dar imported fuses either - I suspect this to
be a case of xenophobia.



God, these polished turds for tubes, must have a great history of shorts
now!!!!!!

Damn!!!!!!!!!!!!!

Fuses too!!!!!

My God, I'm surrounded by Polished Turds!!!!!!
I guess it takes one .....!

It is also doubtful that anyone can discern any differences
among tubes built within specification

Well, would you like to listen to the difference in the performance of a
400-PS with
GE-6550A's in it, vs a 400 with 6556-WE's after a years worth of equal
mileage down a VERY
hard road.

My ears have not been circumcised as perhaps yours. Are you sure that it is
your ears that have not traveled that very hard road??


To a player of a 400-PS, the difference is day and night!!!

Unless he or she happens to be deaf

You audiophile guys think you know always the last word on sonics.
LOL, yeah,... like that makes you all expert on what the musical guys use
for the music
production.
Come on, jump into our world!!!!!!!!!!!!!!!!!

Your world appears tainted with misinformation and apparent misguided
prejudice. I like it here - thank you.


Besides, without us, you'd have just sound effects to listen to with your
hair splitting
intensity for audio!!!!!!!

Without "us" -- who be "us" - I never heard your name colocating with
Lansing, Frank McIntosh, Phil Specter -- etc???

Hmmmmmmmmmmmmmmmm...........................!!!!!! !!!!!!!!!!!!!!!!!

You sound like a burnt out roady - not an engineer

Whose flute?

In guitar amps, it's easy. Even
untrained, non-guitarists can
hear the difference. Even drummers.
Even us trombonists. Even in a
blind test. Piece of cake.

Chocolate cake.

Yum!

I would guess any tube whose structural elements are rigid enough to
maintain spacing and does not readily "short" when subject to
shock/vibration. This can be easily determined by energizing the amp with a
100 Watt clear light bulb in series with the line, and with all the tubes
installed, tapping on the tubes with a rubber handled screwdriver - while
observing the series line light for changes in luminance. Changes in the
light would indicate structurally unstable tube elements - meaning it is
likely the amp/tubes will short during service. Otherwise, I doubt you would
be able to discern any quality difference. The SVT is also tough to
balance - from what I recall, and can be very touchy.

Most people have switchable bulbs on their bench autotransformer
panel. But the sorts of element vibrations or excursions thought to
be at play (emphasis "thought") are a good deal less than a short
capable of this observation. Most experienced people tap for shorts
on a tester,too. But such shorts would be major noises and failures
in an onstage 400-PS (translation: it would quickly sh*t the bed).

Humorously, you may or may not wish to reconsider calling yourself a
PE in public discussion. It is like ship captains who call themselves
"Captain" in the company office when they are promoted to managers-
they are usually useless. :-) Besides, people can get a PE to
approve things or otherwise make them liable for what they do or say
as one. Guess why I don'tg.
