There is no reason for outrageous power supply voltages with a "monkey" even when using a 300B. Here is my latest version. Note it is not a "full monkey" as the cathode resistor of the driver tube is not within the OP tube cathode resistor chain. The LED bias eliminates the need to do so as there is no cathode capacitor to eliminate. The 6N23P can only just barely drive the 300B to full output so this is not ideal, more of an experiment to try the 6N23P. However, I can easily drive my efficient speakers with a 2A3 amp so I don't need much power.

My next iteration of this amp will be with "stacked" power supplies along the lines of the Komuro 300B. Maybe the is more than meets the eye with this simple circuit, but my own feeling is that the direct coupling and elimination of the grid resistor for the OP tube makes all the difference. I really can't see myself ever going back to cap coupling the driver to the OP tube.
