But i recall never seeing any smoke until now coming from it. I checked tubes associated with it and none were shorted. I noticed that the resistor has a connection to G1 of the AGC amp tube. I had been adjusting the AGC in hope it may have given me a better picture, not sure if its set too high, but I dont think adjusting the AGC would cause this.
That resistor is a red flag odds are there is a short or a mis-biased tube drawing too much current through it. Do voltage checks in the area around that resistor and on any tubes it feeds.
