Hi Paul,
Well, I've checked already for DC on my lines... none there. This transformer does run pretty hot, though. After a couple hours idling the laminations are too hot to touch for more than 1/2 a second or so.
I tried tightening the through-bolts further, but that didn't make any noticeable difference in hum. I just did a test, and, with the amp pretty well warmed up, I can hear it pretty clearly from 15 feet away. It sounds, though, like the transformer is resonating at some harmonic of 60Hz... at least, there are definitely overtones to be heard.
Can you recommend a place that can do the CA treatment you mentioned? I had contacted Paraline since they are the original manufacturer for this transformer.
Thanks,
Paul
