Interesting thing...as I said before, the horizontal oscillator is putting out a clean 15.75 KHz sine wave but when I look at the waveform on the plate of the 6AL5 Horizontal Sync Discriminator, the waveform trace looks fine...it's just unstable and jumping all over with instability in the picture. I don't know if that means anything other than crossing the oscillator off the troubleshooting list. The 6AL5 is new and I've put 3-4 different ones in the socket with the same outcome.
