WARNING: Tube/Valve amplifiers use potentially LETHAL HIGH VOLTAGES.
Building, troubleshooting and testing of these amplifiers should only be
performed by someone who is thoroughly familiar with
the safety precautions around high voltages.
Is it possible to drive a 845 push-pull power stage utilizing the signals taken (through capacitors) from the anode and the cathode of a 300B working in a SE configuration (... with the anode connected to a 3-3.5 Kohm output transformer and the cathod connected to a RC) ?
A 300B concertina? Anode load is usually resistive here though. If your already using a transformer, it makes more sense to use a center tapped secondary for phase splitting.
