Took out every transistor, module, and tube one by one, and squirted Deoxit into every socket. After that, I got a very nice, sharp, vivid picture with well defined lines on the NTSC generator ONLY. After about ten minutes, the definition of the NTSC color bars went away, and it was just like it was earlier today with very poor definition. I was able to get a somewhat watchable picture on UHF 16, but VHF 3 still has contrast through the roof. AGC does nothing to compensate for too much contrast. Thinking either a bad electrolytic cap or transistor.
