How does swapping V2 in the 25w Mark V equate to what is being talked about in that thread? If I've read the thread correctly, V4 and V6 in the 90w Mark V are being swapped out with the 12at7. Here is what that manual says about the 90w tube layout:

V4A- Reverb Driver/Send
V4B- 4th Gain Stage CH3

V6A- 6th Gain Stage CH3
V6B- Effects Return Stage

Here is the tube layout from the Mark V 25w version:

V1A- Input Stage CH1 & CH2
V1B- 2nd Gain Stage CH1 CLEAN & FAT 3rd Gain Stage CRUNCH 2nd Gain Stage CH2

V2A- 2nd Gain Stage CH1 CRUNCH
V2B- 4th Gain Stage CH2

V3A- 3rd Gain Stage CH1 CLEAN & FAT 4th Gain Stage CRUNCH
V3B- 4th Gain Stage CLEAN & FAT25

V4A- Reverb Return
V4B- Reverb Send

V5A- FX Loop Return
V5B- 5th Gain Stage CH2

V6A&B- Driver/Phase Inverter
