I don't have a PC case, and real PC case has too many holes.
For not too much more than that, I was thinking that
one could build a
much larger tube amp, over delivering 200W RMS... ok, well... I stand
corrected; actually, just the Hammond iron alone is going to cost
nearly US$600, plus a few hundred dollars more for new tubes. Still,
it's a heck of a lot less expensive than what people are paying for
assembled tube amplifiers... still, too expensive for me at this time.
Is what you're building a class-A triode amp, by the way?
Nope, a class-A ultra-linear amp. :)
A Push/Pull amp gives more power, but I want to try a
Single Ended amp with low cost tubes. Add $300 more for low
cost Direct Heated Triodes.
Other good news... not sure if anyone else has heard
it, but Western
Electric plans on resuming the manufacture of not only the 300B tubes
here in the U.S., but possibly other types of tubes as well. :-) After
resuming the manufacture of 300B tubes a while back, they had to
reloate their equipment, and production stopped in 2002). That's right,
audio tube production in the U.S., hopefully in 2004!

The last time I checked they still were rebuilding the factory.
The other $100
is for the
box to mount the stuff on,and keep the cat's paws off the tubes.
Hmmm, wouldn't a PC chasis, some chicken-wire and some bailing twine
have been far less expensive? :-) Somewhere around here, I think that I may have a book
from the 1970's
pertaining to building a computer from TTL... will have to look for
it. I only recall Byte (an article by Steve Ciarcia?) having
published an article about building a computer from chips, but I think
it used a microprocessor... hopefully someone can prove me wrong about
that.
I dumped Steve when his project was a PC clone. Byte went down hill from
then.
BTW does anybody have BYTE and other early computer mags on micro-fiche,
all the local libraries have thrown them out years ago?
