For what it's worth, all of the HV caps in my Swan 350/117 needed
replacing. They big ones for the transmitter were oozing gorp.

Yours caps are probably from the same era, and should be replaced too.

The 117 powersupply is solidstate, and so the crackling is very likely
the filter caps preparing to go blorp all over the place.
