Gerald Mielke:
When you say that the "Bplus is fine"...... does that mean that it is
holding regulation and the proper voltage when the AC line voltage is varied
+/- 10% with a variac? You may want to check solder connections near and
around the high heat producing parts and especially including the flyback,
h-drive xfmr, power resistors, power chips, etc.
By the way, you really need to post the model numbers and post some more
technical troubleshooting results..... dust off your DMM and your Scope and
do some basic troubleshooting and visual inspection at your end..

everything looking good, they just cut off. seen anything like this?
