The 460 khz signal goes through loud and clear. The shadow meter was open so I replaced it with a 1.2K resistor. As far as the DO NOT ADJUST trimmers. I counted how many turns until they were fully tight and after cleaning the whole tuner assembly I returned the trimmers to their original setting. This is a tombstone. One thing I have noticed is that when I remove the grid cap from the QAVC tube #78 nothing happens its like the tube is doing nothing at all. I will start measuring the plate, screen grid and cathode voltages. Appreciate your help !!
