The Perseus I bought about nine years ago, in spite of otherwise sounding very nice, has always had a noise problem. Essentially a high-pitched hum/low-pitched buzz- 60 Hz harmonics, I assumed, at a constant level, not VC-dependent. Had just lived with it lo these many years but was getting frustrated. Wasn't convinced that the factory was going to be helpful, and thus decided to take a whack at it myself. So I removed the top, removed the toroidal transformer retaining nut, and propped the transformer up on a plastic foam block so that it was raised up about three inches from its usual position at the bottom of the case. Voila'! Noise reduced about 80%.
However, I didn't want to use it like that, as I could no longer put the top cover back on. So I replaced the transformer back to its usual spot but tried rotating it about 90 degrees, the wires fortunately being long enough. Now had noise reduction of about 70%, and I can live with that. Would love to hear any insights on this from anyone in the know.
