I will be checking the AGC pot for smooth voltage division, the noise gate transistor and the sync sep tube for proper bias/waveforms. the PCB's look to be fiberglass, tough, no heat damage like seen on RCA PCB's. The tuner is very stiff, like hardened grease or something seized on the channel drum. UHF does not turn at all. focus voltage did not seem to move with the adj of the coil, stuck right around 4kv, IIRC I can see movement on other sets that use the same focus circuit when reading with my simpson 260 in the 5kv mode. Focus is soft and did not seem to change. Perhaps the focus rectifier stick.
