I've got this set on my bench right now.

Injected the signal, nothing, so decided to start by measuring plate voltages starting with the RF section working my way forward. I got squat. 0V. No plate voltages on the RF amp (6J6), nothing on the mixer (6J6), nothing on the oscillator (6J6), and went forward to the 1st video (6AG5)and 1st audio IF (6BA6), and nothing.

My eyes are going buggy looking at this schematic to try to figure out where the plate voltages originate. Can anyone clue me in?

BTW, Al changed the tuner over from an identical set, and no change.
