All 4 of the diodes should be replaced with the new part# 1N4002S or NTE 116. and it would also be a good idea to replace all 4 220mfd caps in that power supply circuit.

Make sure all grounding scwews are all torqued down both inside the unit and also the back panel screws.
Good Luck!

I am having the same symptom, but on inspection, I found that the wires plugging into CB102 pins 1 & 3 are shorted together. Since these lead to the transformer, does that mean my transformer is bad? If someone with schematics could tell me, or if someone with a working receiver could just tell me what resistance they measure between those wires I would really appreciate it.
