hello all, here i am again begging for more advice. i recently acquired an amp from a hammond l100, its circuit is an ao43. it runs 2 12ax7s, 2 el84s, a 5u4, and a 12bh7.
schematic here

or full manual here with clearer schematic (amp is the reverb/power amp and is in the top right of the schematics)

i was considering gutting it and starting a scratch build but, am curious if anyone has any advice on how to give her a bit bigger mouth so to speak. id like to bias v6a to be used as a second preamp stage, and also would like any advice on how to bias the 12ax7s to get some breakup. currently it seems to be just a power amp, also having some issues figuring out where to add volume pots, would like a preamp volume and master volume
currently all i have done is bypass r337, run a 1/4" jack into pin 7 of v6b and connected c302 to v8b pin any advice is appreciated
