[TechAssist] Re: [TechAssist]UPD*** Emerson part ID TC2555D R521

I replaced the REG, HOT, resistors 4.7 and 47 ohm.
1/160, 100/160v replaced.
REG and HOT are still getting real hot after a few minutes.
B+ was at 130, adjusted B+ p.o.t. to get B+ at 120v, won't go any lower.
What should the B+ be on this unit?
