Can you disconnect the wire to the 7B7 cathode? I'm trying to determine if current is flowing through the 7J7. If the other cathode is disconnected we can measure the cathode voltage of the 7J7 to see if the oscillator triode is conducting.
On second thought, don't do that. It takes the bias off the 7B7 and it may be detrimental. Let's see what the voltage measures on both sides of resistor 33.
