No better idea. I've read in times past of someone sandwiching some compressible material between the transformer and the supply top cover to quell or reduce the hum. I have an RM-50M that hums in this manner and fortunately it is not loud enough to keep me from listening to the K3 at about 8 o'clock with external speakers. 73, Nate, N0NB -- "The optimist proclaims that we live in the best of all possible worlds.
