Being a huge fan of old Ampeg amps, I have to post this link, I think theyhave the schematics for every ampeg since the from the early 60's up tothe 80's. A good starting place if you want to base your design on an existingamp. (my personal choice, the R-12-R) Hope this helps! -Nate

Eric Barbour is a really smart guy. He can, however, get a bit irritated
(especially if you mention the word "nonlinearites" anywhere nearthe word
"tube"). I don't think he likes guitar amps too much, but he doesknow quite
a bit about them, as one would expect.

I know nothing about your idea of a protobaord type arrangementfor tubes,
interesting idea, but probably not good for a stooge like me sinceI'd
probably change out one part, without changing the other (poof!).I've never
done anything with tubes (too close to Larry's scary voltage levels),but
I've always thought those circuits to be so simple as to not reallyneed a
protoboard type device (hey! Isn't this where the term breadboardcomes
from?).

I have been somewhat tempted to do something with tubes though.As Paul said,
some people are using tunes to build synth modules. But I'm moreinterested
in building a 50 watt amp head, and I seem to remember a book thathad plans
for an amp like this, maybe even a kit was associated with it.I can't
remember the book's title though.

I will, however, recommend the book "The Tube Amp Book: 4.1th Edition"by
Aspen Pittman. It has a huge collection of schematics (like severaldifferent
schematics for Fender Deluxes with maybe only a couple of resistorchanges in
each).

And I always recommend Antique Electronics in Arizona -- a greatplace for
tube (and associated guitar amp, and antique radio) resources,and great
people too!

I'd like to hear how this goes Dave.
