Magnavox 25TR12 C102 Chassis 25P606-00AA wont power off

In the schematic, it says I should have 134vdc on the base of Q420, I have
160vdc. Is that to much? or is that normal? Thanks.

Sounds like Q420 might be shorted. These are linear supplies,
so they don't mind being brought up slowly on a variac, if you
have one. B+ should follow the input up to about 14V and stop.
If it keeps rising, you can shut down before burning stuff up.

Also are you sure you replaced C432 with a good 100uf200v capacitor?
When this is bad, power supply runs high and sometimes causes this
resistor to burn.
