You have to love Craigslist. This amp was the first amp that I had picked up to start doing modifications to. There’s plenty of room inside for putting in just about any kind of preamp that you could think of.

Tube Line up:

3x 12AX7

3x 7247

2x 7868

I’ve never messed around with 7868s before so this will be an interesting amp to do some tweaking to. As you can see below the amp is completely point to point and the layout of the terminals is perfect for tinkering and rebuilding the preamp section into something insane.
