A friend of mine just brought over a pair of N.O.S. tubes. They have a
spray coating and are labeled 4046A but have no manufacturer's name. It
is a medium size "ST" shaped bulb with a grid cap and a British (?)
style 5-pin base. Is anyone out there familiar with it? Is there much
demand for it? What do they usually sell for?

Thanking you all in advance,
Tom

No such tube in all of my books, except an equivalent CV number in the
AVO valve data manual: CV244.
The later edition of this manual lists CV244 as being a replacement
for AF2, a Philips RF/MF penthode which indeed has a 5-pin European
base and a topcap.

A very limited piece of info can be found he
http://www.mif.pg.gda.pl/homepages/f.../039/a/AF2.gif
And here some more data:

It's probably worth something to European vintage radio restorers,
I doubt such tubes were used in the US.

Thanks, flipper.

Yes, that's definitely the one. Is there any market for those tubes?

Thanks,

Hey, you're welcome, too.

This is definitely the last time I'll spend half an hour looking

Sander,

Unfortunately no good deed goes unpunished . . . .

More than once have I taken the trouble to copy a schematic and mail it to
someone for free without the benefit or courtesy of an acknowledgement. But
on the other hand, sometimes you can make a friend . . . .

Yeah, I know.
I resent my comment and take it back.
I'm suffering from severe pain at this moment and did hit "send"
before thinking twice.

I apologize, Sander. I certainly appreciate the work you went to for
me. How I blew off thanking you for it, I can't explain. Through my
embarassment I wonder if I'm finally succumbing to Alzheimer's or
something. I feel really bad.

Anyway, please continue to be of help to the list...don't hold my faux
pas against the rest of the people here. I'm sure the average guy is not
as rude and crude as me.

Again, sorry for oversight,
Tom

Hmmmmm. That's quite a bit of dough. I wonder where a guy would go to
find anyone who would be interested in them.

Tom,

I should be the one to say sorry.
I was in a state of severe pain at the moment I wrote it, and the
message went out before I even knew it.

I'm a little cranky and impulsive sometimes.
I get treated for that ;-)

Heck, I'd treat you to a Baskin-Robbins if you were here! Well, I would
if there was one within a hundred miles of here, anyway.

Cranky and impulsive? People who *aren't* cranky and impulsive are what
is usually known as "dead" ;^)

Tom

[Tom]

Really? You think there would be enough people who would see them and
bid on them? Well, I might try that. I've got some of this guy's
oddball tubes on there right now, like a pair of Cardon C-183's and some
used 2A3's, etc. If it's of any interest to anyone, my ebay i.d. is
"theponyengine"

Thanks for the advice,
Tom

I already had a Haagen-Dasz in your memory this afternoon.
Remember me to collect $1.20 next time I'm around your neck of the
woods ;-)

Well, actually I learned a lesson today: I'm just the opportunist that
everyone else is ;-)

| Well, you've sold tubes before so you know more than I.

Well, I doubt it. I live in a very rural part of Iowa and after I
retired from the truck business I ran into a guy who asked me to sell
some electronic stuff for him. There were some tubes in there that
turned out to be Mulllard GZ34's and I guess I did pretty good for him.
Since then, various folks around here (mostly farmers and ham operators
and old TV repairmen) have given me electronic stuff to sell for
them...like these peculiar 4046A's. I've had farmers bring in everything
from 2A3's to a W.E.101D that they've found stashed in haymows and
elsewhere!

So, I've studied up on tubes. But still, I only know what I've been
told. I'm sure that's less than you. I've been a ham operator since I
was a kid, but that's about the extent of my electronics background.

As far as these 4046A's go, I'm lost except for what you and Sander have
told me. If I can't find anybody who uses these things on here or
elsewhere on the internet, I'll probably end up doing as you suggest and
putting them on eBay in hopes that somebody sees them.

Now here's something else interesting about these. The boxes were
unopened and marked "VT-122"(!) From what I can read, these aren't even
vaguely similar to a VT-122 which apparently was a high-power WWII radar
transmitting tube. I don't think they would even fit in these boxes.
So that's another mystery to me.

Anyway, all I know is what I'm told.

Thanks,
Tom

This is actually possible.
The "VT" designation was also used by the British Post Office.
Guess what, when I looked it up in my AVO manual, they correspond to
the CV244, which in turn is the AF2 I mentioned before.

Myth busted! ;-)

How they got buried in an Iowa hay stack is the *real* mystery.......

--
"All amps sound alike, but some sound more alike than others".

[Tom]

That's interesting. It probably explains the VT designation. Are those
other two numbers any more well know than the 4046 designation?

These two didn't come from a hay-stack, actually. The fellow who
brought them here works in a mill by day, but runs a TV and antique
radio repair by night. I have no idea when he sleeps. The thing is,
even *he* doesn't have a clue as to where he got them. He bought out an
old radio and TV repairman about 20 years ago when he went into the
business and they might have been part of the deal. Or it could have
been in any of a number of auctions that he's been to over the years.

Iowa estate auctions can be an amazing thing. The original guy who
started bringing tubes to me went to one in a town of about 10,000 and
got a bushel basket of tubes for three dollars. So I stop at his shop
the next day and he holds up a Cunningham CX-350- still in the box -
that was in the basket. "Are these worth anything?" he says.

The same guy found some variant of the W.E. 101D - it had some crazy
number on it like 89328 or something - cleaning out the upstairs of his
120 year old building. And it tested like new! My Hickok is the
Western Electric version, so it can test those.

Which reminds me, a guy gave me a couple of Hickok W.E. "Cardmatics" in
payment for a bill. One is missing about a third of the cards. They
both look good but need work. I wonder if anybody could use one of them
for one of those computerized curve-tracing conversions that I've seen
on the internet. Those set-ups seem pretty pricey. I wonder if that
fellow moves very many of them.

Anyway, thanks again for the info on the VT-122.

Some yank tried to hide from the Martians that were about to invade in 1955.
He grabbed the tubes and bottle of Jack Daniel and fell asleep.
We woke up a bit headachy and saw Martians but forgot the tubes....

Elementary dear Sander.

LOL!
The ways of our imagination.............

My explanation would have been more prozaic, boring even.

They were probably brought to the US by an air force officer, who
bought a radio set or even some measuring gear in the UK, where he was
stationed during WW2.
The 4046As were spares for it, and forgotten after transistors came
into the picture and the radio or gear was tossed in the bin.

The things people keep hidden in their attics...........
