CTC-5 Service Info Sought

[old_tv_nut]

Bryan,

Let me clarify - the case when I had weak lock, the H frequency was off by some fixed amount, which would correspond to multiple stationary diagonal bars if I had been able to see it on the CRT. Once I hooked up both channels of the scope, one to the H waveform and the other to video, I realized I was off frequency. When I got back to the proper combination of frequency and waveform, the lock became very stable.

If you are seeing a proper picture that is on frequency, but the lock is unstable, then it's something else that isn't bad in my set. Maybe those micas or maybe a bad input signal level.
