His work is pure art. The tone stack execution is perfection! :worthy:

How does it sound?
Thanks, it sounds like you would expect, like a 12,000! I had the input voltage at around 90 volts for the longest time but decided to try it at a higher voltage. Recently bought a Eurotubes voltage probe for biasing and discovered that it had been biased a little cold the whole time so I settled on 105 volts after some messing around with it. It's got more clarity than it did but still plenty of gain, really fun to play with my ash Charvel clone. I have considered buying a M****n C1998 OT to replace the 132 just to see the difference, but that'll have to wait for now.

To be honest though, the 45/100 I built is far and away my favorite, that thing smokes!! The split cathode, while awesome, is kind of a one trick pony to me. Shared cathode with the 56k/250pf tonestack and 0.1uf P.I. couplers makes for a big glassy powerful sound, especially with the KT66s. A different kind of mids and more bass than the '68 circuit, it cuts through the mix better live, it just has AUTHORITY. I just started on a Black Flag JTM50 and I have a feeling it will be just as fun.

God I love building amps...

I am new to building but DO KNOW art when i see it :shock:
That is incredible work! :thumbsup:
I can only hope to get a quarter as good as that, i am just starting out but have a knowledge of most of the components just dont know where they go and why/how they effect the final result :oops: :lol:
