I created this graphic from the manual tube task chart. I also used some information on the schematics I have seen for this amp. The only thing I left out was the how the clean channel is managed before the FX loop as it has a pair of op-amps to compensate that channel. The clean channel is the only part of the amp that is identical to the Electra Dyne. The Triple Crown also has a similar clean channel but different tube locations. The hi/lo channel is fully independent of the clean channel. You can literally remove V1 and V2 and still use the clean channel. The same holds true if you remove V4 and V5 if you use only the hi/lo channels. Obviously, removing V3 you will get no sound at all. Also, the reverb circuit runs in parallel to the FX loop. This is similar to the Electra Dyne and the Triple Crown.
