Ken, Look at pin 8 of the vertical IC(LA7837). I have found a bad zener(which is not marked on the diagram) on two CCR095s that caused bad vertical. The zener is an ECG5024. Maybe this will help.

I had already replaced C6 along with C4 & C14. Bridged R6 with 1K resistor. Set better, but still slightly stretched at top. Am trying to decide whether to ship it or replace the 1K with a trimpot. It makes me nervous in modifying a circuit. I just feel like I missed the real problem and must compensate. Everybody, please understand, this is not directed at Jeff. He's a friend and has provided help to me and most all of you, but it is rare that we must re-engineer a circuit.
