My MIR has developed a hum that is telegraphing through the speakers. I am not sure when it started, but I recently changes speaker from 96-ish dB sensitivity to 99-ish dB sensitivity. When I take the top off, I can hear that the hum is coming from either the power transformer and or the choke, but neither seem to be vibrating when I touch them. Any suggestions as to how to fix. It's annoying, but not un-listenable. Thanks in advance. "Anyone who understands jazz knows that you can't understand it. It's too complicated. That's what's so simple about it." - Yogi Berra.
