Here we have the Sophia Electric Model 91-01 300B
It in no way resembles the WE 91 circuit.
Look closely at the FWR soldered to the pins.
Yes, hum pots, one for the DC 300B and one for the 6SN7.
Here's the one I received for repair. It's either a hack job from "a" previous owner, or (IMHO) the transition unit from the motor run to the panny lytic for C2.
A quick fix as the cathode bypass cap was NOT soldered to it's Rk mate.
