Try changing the 36 autodyne converter tube. Its a marginal oscillator circuit at best and unless the tube is in top shape it can be a bit unreliable as to oscillation. I had to try several in mine before I got it stable.

Check the voltage across the wirewound bias resistor. I get about 14-15 V across mine. Much more than that and it might be drawing excessive current. My transformer gets warm, but not uncomfortably hot to hold ones hand on.
