Quickie question re: MKIII tube map

[edward]

I searched and can't find the answer. Can anyone tell me what each preamp tube on a MKIII head is (Simulclass, Graphic EQ, no reverb).

And as other Boogs, should I assume that (looking from the rear) right-most tube is V1? I've got three AX7s in a row then a 4th. Is that odd 4th tube spot the PI? Thanks!!

The 4th one that's not in the row with the rest is usually the phase inverter (v4).

OK, cool. And I presume the one with the can is V1. So does anyone know specifically what V2 and V3 (and their respective halves) are responsible for? Thanks!

v1 (the one in can) is the input stage, v2 I believe is for r2 and Lead, v3 is for the lead channel only, and v4 PI.

v1 (the one in can) is the input stage, v2 I believe is for r2 and Lead, v3 is for the lead channel only, and v4 PI.

V2 is also for the FX-loop, but when r2 is engaged it also delivers a gainstage I think

Here's a link to the Mark III manual. The manual is imperative for this amp.
