Also, if you look at the cathode load resistor for the output stage 12AX7 in that circuit, it looks like its value is only 15k ohms. The voltage chart says there should be +19VDC on pin 8 (the cathode of the cathode follower section). That means the plate current for that stage is 1.2mA, which is plausible. But a 12AX7 running with a 15k load?
