My PA76 buzzes a bit. But I had another PA76 transformer from a guy who
swapped it for a Dahl and that one sung like crazy. Used it for a ton of
key down power tests on an amp I was building and it never showed any other
side effect than rattling.
On the other hand I have had a diode and a couple of filter caps go out in
my PA76. So you may want to check those for good measure as well.

Hi Steve,
I agree that any transformer can have a winding replaced, but would it be
cost effective, particularly with a small transformer? It would probably
be
cheaper to buy a new unit.
Just have a go at it.
