when the transformer went in my TS520SE

Your what?

For the benefit of those who lack basic google skills (or CBA to
google), it's a 1970s Kenwood "Ham Radio" shortwave transciever designed
to be run off mains power (120/220/240vac). Presumably he meant the mains
transformer in the integrated supply which, in this case would have been
a special to provide heater and HT voltages for the valves (vacuum tubes)
as well as low level DC voltages for the transistorised portions (it was
a 'Hybrid' design relying on valves in the final stages of the
transmitter to achieve its 100W PEP RF output power rating).
