Hi Tom,
Since I have no sweep, I have no waveforms on any of the pins you mention. I am now checking resistors, diodes and voltages on all of the trigger and sweep circuits but so far, I haven't found anything unusual. It HAS to be something fairly simple but so far, I haven't found it. I was hoping there was a common problem that led to both channels losing sweep. I won't give up until I find it but it's very frustrating at this point.
Thanks again for the suggestions!
Steve
