Function of preamp tubes in a Mk II

Since there are so many preamp tubes in the Triamp Mk II, it is hard for me to understand what time is doing what. Does anyone have a breakdown of what each position does in the amp? If you do, please share! Thanks!

Amp. 1A and 1B = tube 3 (E83CC)

Amp. 1B = tube 2 (E83CC)

Amp. 2A and 2B = tube 5 (E83CC)

Amp. 3A and 3B = tube 4 (E83CC)

Amp. 3A = tube 6 (E83CC)

Amp. 3B = tube 7 (E83CC) or 8 (E83CC)

Amp. 2 and 3 = tube 4 (E83CC)

Amp. 1 and 2 = tube 1 (E83CC)

Tube 9 is phase inverter

12AX7 can be used in place of ECC83

Power tubes are EL34 or equivalent

Fantastic! Thanks for the breakdown

I know this is an old forum...

but, whenever the amp calls for an "E83CC" it's not actually calling for that type of tube. As far as I know JJ is the only one making a true E83CC frame grid tube. Any other tube that says 7025/E83CC just means that it's a select high grade ECC83 (12AX7).

Layout:
V1 - Amp 1 & Amp 2
V2 - Channels 1B (Preamp)
V3 - Channels 1A & 1B (Preamp output)
V4 - Amp 2 & Amp 3
V5 - Channels 2A & 2B
V6 - Channel 3A
V7 - Channel 3B
V8 - Channel 3B
V9 - Phase Inverter

Channel Routes:
1A - V1, V3, V9
1B - V1, V2, V3, V9
2A - V1, V4, V5, V9
2B - V1, V4, V5, V9
3A - V4, V6, V9
3B - V4, V7, V8, V9
