Got the chassis on the bench. Found at least part of the problem. V1, the 6J6 RF amp, has only 88.2 VDC on pin 1 and 84.8 on pin 2. Should be 145 VDC on both.

V2, the 6J6 mixer, voltages are right where they should be.

V3, the 6J6 oscillator, pins 1 and 2 are high. Should be 75, I'm getting 98.

Problem has to be in those small white mmf caps that I didn't change. Are they anything special, composition wise?
