which ones?


** All of them.


It's not like I haven't built a bunch of guitar amps since I was a
teenager, both tubes AND transistors, nor seen a number of schematics,
nor reverse engineered a Fender amp to build a custom amp based on
Fender's circuits because someone wanted me to, nor having played guitar
since the 1960's, nor having re-worked the electronics on guitars a few
times [including putting a 5 pos switch on a Hondo strat copy that had a
3 pos switch for a friend], yotta yotta.


** Fraid you have no learnt much.


OK - which of the things I said were "wild guesses" ?


** The whole lot.

keep in mind that the tech manuals said something I'm agreeing with.
YOU are disagreeing with the tech manuals,


** Never said any such thing.


A typical old amplifier:

(in this case 75k - I've seen as high as 220k, but on average, input
resistors on the shared input are around 100k, which if you think about
it, isn't a whole lot different from 75k or even 68k when you average it
all out)


** Average of what? Not amps sold for sure.

Vox, Marshall, Fender, Peavey, Music Mann and countless others ...



shows volume and tone controls are 250k. I have seen as low as 50k, but
typically 100k as I recall.


** With a 10 kohm source (at 50/60 Hz) and turned to half value = what?


My guess ..


** Another wild guess ????


And I still accept what the tube spec sheet says


** You have no ****ing idea what that 50s doc refers to or if it has any relevance to guitar amps or modern examples of 12AX7s.

FYI

I have 50 years experience designing and repairing guitar amps plus LOTS of other types of audio gear - including tube condenser mics.

You came here on a damn silly notion & got an expert who pointed that out.

You get to like or lump it.
