I had an unfortunate accident and broke a box of old tubes I had lying
around. I found one 12au7 still intact and decided to give it a try in
my Peavey Classic 30. I don't know how old or how used the tube is. Here
are my findings with a Strat....with two older stacked humbuckers that
sound very Stratty to me. One SD, One Dimarzio.

In V1: It was like the 30 watt amp became a10- 15 watt amp. It basically
made the amp into a straight ahead bedroom amp....clean channel volume
needed to go up to 4-5 before it became normal playing volume where it
was loud at 2 previously. For those of you who want to lower the volume
of your amp for house use....you should consider this change. Would not
be loud enough for gigging this way though. Gain channel sounded about
the same, just lower in volume.

IN V2: Does not affect clean channel. Gain channel sounded very clean
with gain up to about 8-9. Gain all the way up added just a bit of dirt.
Very much like the clean channel turned all the way up. Would really
work well as a boost channel for clean channel and use a distortion
pedal for general distortion sounds as necessary. Sounded very nice and
seemed like something that can be useful.

IN V3: Made the cleans a bit cleaner, and a bit lower in volume...not by
much...but sounded very nice. On gain channel it seemed to make the
distortion a bit harsher, maybe a bit more trebly...not bad just
different. Volume was just a bit lower.

I have to get some more tube types to really play around with it....but
the AU7 being the lowest gain of all is a good starting point.

Anyone want to sell me an assortment of tubes cheap?...don't need
many...just a few different types.
LOL.
you can become the resident tube testing guy.
how are you gonna get on when they send you a set and want to know if the
biases are matched ... on a classic 30?

DOH!...and I thought I had it all figured out ;-)
