Well, I tore into it yesterday. Once the covers were off, the sound was very quiet though it was still there. Seems the metal covers are acting like an amplifier. Everything was bolted down good and solid though, and the filter cap off the transformer checked good for both ESR and capacity. Looks like I need some way to deaden the chamber effect of the metal covers to keep them from amplifying the sound. If I hold my hands on the covers, the sound becomes almost non-existent.
