Curious what each preamp tube controls what in what channel Thanks
From the JVM forum
1st valve -1st gain stage
2nd valve -2nd and 3rd gain stages
3rd valve -4th gain stage/cathode follower
4th valve -noise gate recovery/serial loop buffer
5th valve -phase splitter
V1 (under the metal can), V2 gain stages, V1A, V2B are used in all modes, the rest is switched in/out depending on the mode.
V3A: tone control buffer.
V3B: channel mixer/ parallel loop send
V4A: FX mix
V4B: Reverb Mix
V5: Phase splitter
