The formers of transformers often go slightly conductive, some are only card, some soft paxolin. I have found that switch cleaner soaks in to them and makes matters worse.
The switches in Bush VHF radios do the same, the HT leaks across. I have stopped using switch cleaner as an aerosol, preferring to use it on cotton buds and just clean the contacts.
It could be that the solvent from the varnish did the same?
Nice fix, hope it gives good service after all the work.
