My next step was going to be to inject a signal into the grid of the 1st video tube to check everything out from there. But I was leaning towards the problem being the tuner. The LO not running makes sense with the condition I have. Thx.
What might cause this? I have not inspected this tuner b/c it is difficult to access and must be removed to even inspect it. Guessing there are caps and resistors inside that if are bad might lead to the LO not running?
