Hi John,,, I have experimented
with different preamp tubes in
several different amps and its
a hit or miss situation. Seems
to work out for me better in
some amps than in others. Right
now I use a 12au7 in the first
gain stage of my Princeton amp
and love it. It matches up well
with that amp and the OD pedals
I use with it better than the
stock 12ax7. Try it. Also try it
in different stages too. Might
find something you like better.
It is just the gain factor that
you are tweaking. You can dig
around this web site for the
gain of all the different tubes.
As far as the DIY project you
mentioned, I am a newbee to this
DIY thing so I'm not qualified
to comment on that. I'm not
familiar with the Hilgen amps.
There are probably some
"adjustments" you can make to
your Peavey amp to get more head
room (like swapping out preamp
tubes) but the EL84 is by nature
a dirty, raunchy, Marshally type
tube so it will be tough to get
the Fendery type "shimmer" I
think you are refering to.
Another option would be to rebuild
the amp with 6v6's. I believe
your transformers and such would
be a decent match for them. It
would involve research and work
but would be cheaper than buying
a second amp. Jim Kelley amps
that I've checked out in the past
used 4 6v6's I think and those
are some sweet sounding amps!!!
Lets not forget that Jimmy Page
used this little tiny amp (Supra
I think) to get the monstorous
sized tone on that classic first
Zepplin album. I think the Supra
amp used little 6v6's also. Its
a great tube...
Best luck with it...
