41-287 No voltage from secondary of transformer
#2

Hello and welcome.

What kind of voltage do you get when you measure from plate to plate of the 84 rectifier tube? (Tip: Measure this as AC volts, not DC volts.)

If you are not getting anything here, chances are the power transformer is dead even though it did not smoke or leak wax.

Be careful! That AC voltage will be around 525 volts if the transformer is working!

Also, how did you replace the Candohm resistor? With individual resistors? Did you remove the old Candohm (multi-section resistor) from the circuit entirely?
