So, the chart is mislabelled? Because the idea behind the naming convention is that V1 is first, V2 second, etc...Hehehe.. V2 is the first tube/socket to be hit by signal. So, V2 is essentially what would be V1. V1 is V2. The markings on the board and the diagram are correct. I know- huh? Yeah, odd. Jeff from Egnater and John have confirmed this, and the diagram is, in fact, accurate.
Flow? signal -> V2a -> gain pot -> V2b -> V1a -> V1b (as cathode follower) -> tonestack -> V3a+b (PI) -> power section.
BTW- threw a set of JJ EL84's in today, and biased both pairs of EL84's and 6V6's. Also threw a Penta 12AX7 into the mix. Stock in V3 still, undecided on V1 and V2; Tung Sol in V2, Penta in V1.. wicked combo for mid to higher gain (old school metal EASILY); Tung Sol in V2 or V1 and my old Brimar ECC83 in whichever I have open does well also, but a bit more buttery. Still have to try a JJECC83S...
Biased and finding what tubes I prefer.. wow. So tempted to simply leave it out of the headbox to allow V1/V2 changes.. OH! It loves boost pedals up front. Adjust to taste, sucker screams, barks and wails!!!
It's kinda like saying the alphabet is b,a,c,d...
