That's a good idea. I will try that.

I have been running the '81 all morning and each time the video goes bad I spray the ULA and each time the video is restored so it is a bad ULA. I don't think fitting the CCB PCB will be useful?

If this is the case, and the ULA is faulty, should I still revert to its original modulator setting and remove my mod as you suggested above?
