This is a old unit, it will have to have the power caps replaced.

Sure sign this needs a lot of caps in the power supply chain replaced.

This may also be why PA doesn't work - shorts in the power filter caps suck power away.

Be sure to keep the bench clear of debris under that PCB - nothing more needs to be said...

Be sure to keep using - if you haven't already switched over to, an in-line 2-amp fuse until you get the power supply INSIDE the radio - stable.

The Power Choke is a simple 3 amp type - so it cooks easily enough but rarer to replace - my last ones were from Digikey in 2015 and they were remaining stock from discontinued.
