resistor value

Interesting circuit. Looks like the Master Volume is not drawn correctly? It has true grid leak bias on the first 12AX7 stage of the "Gain" channel, i.e. no bias resistor. The clean channel would have to be interesting too. I built an EL34 amp with one channel and no tone controls and I like it. A bit less gain than this one though.

Master looks suspicious. The 5M1 and 1M resistors on the first stage should switch places.
