Eric, I have the set running now, but the HOT/regulator heatsink seems
to get pretty hot. Do you recall if that is normal or not?
I replaced the HOT with 2SD1427 (thats what was in there), regulator
2SD1092, 5 caps around the flyback plus C803, R802, R803, R806. Checked
flyback with HR simulator and it was fine. Measured HOT collector
waveform and it is 1050V p-p and shape looks good. B+ to HOT collector
is 139.5 Vdc. This sounds a bit high. Is it normal for this chassis?
Thanks
Gary
