Jeff,
The relay latch at plug-in is because the unit was powered on when failed.
When you remove F470, do you have proper +125 volts on one side of fuse
holder?
If so regulator circuit is OK. Try checking Q471 & Q472 for leakage.

> CE36G18 TAC9708 dead. Relay latches at plug in. 170v B+ 170V on pin 1
of Q801 STRZ5141B all output voltages of regulator pulsing. I've tried
isolating vertical and audio. I replaced Q883, a 6 volt regulator. I do
have the schematic, but it isn't helping. Any ideas would be greatly
appreciated.
