I recently purchased a Traynor YVM-1 (http://www.lynx.net/~jc/yvm-1.jpg). Its a 4 channel tube PA amp, with 4 single 12AX7 gain stages feeding a 12AX7 PI and 2 x 6CA7 power tubes.
It seems like this amp is a great platform to mod and I know a lot of people have reconfigured the preamp to get something close to a Marshall sound.
I guess to start, could I simply copy this schematic as is? (https://robrobinette.com/images/Guit..._Schematic.gif)
Add the grid stopper and cathode res/cap to stage 1 V1A... run that into stage 2 V1B acting as the "cold clipper" stage, use stage 3 V2A as a cathode follower before the tone stack, and then move the master volume after the tone stack before the PI?
Or is there something big I am missing? I don't need this to be as close to a Marshall or any specific amp as possible, just looking for classic guitar sounds.
