I'm thinking that might be part of my problem. Do you have a diagram or a picture showing which wires go where when it comes to the heater and AGC wires for the tuner?
Also another issue I noticed with this TV's tuner was that the section of the terminal strip where the B+ connector goes to was broken so the terminal is just floating in mid air, and only being held into place by the 3 large resistors soldered to it.
Also is the motorized tuning portion of the tuner affected by the 3 tuner connectors or is that independent of that?
