Wow, I didn't know that. Yes I did adjust it. Well, I don't have a HV probe but I adjusted the B+ to be 180 volts. And interestingly, if I monitor the voltage it slowly climbs...very slowly. But if I leave it on for a long time it will climb to around 184 volts and stay there. But it still plays fine when that happens.
The times when it doesn't work, the voltage just comes on way low and stays there (24 volts or something like that). So it doesn't really sound like over-voltage protection to me. But that's an interesting fact to tuck away for future reference!

You may be running borderline on the HV. I believe the K6100 has an
over-voltage proteciton circuit that chuts down the monitor if the HV is too
high.
Did you adjust the high voltage after the rebuild ?
