I recently replaced a bunch of resistors in my Set Monos from janky old beyschlags to Tants and carbon films.
Just today I had my amps running with mys stats off and I could hear my (front end) music coming out of the amps? I thought huh, am I hallucinating this is weird? Put my ears around the amps with the covers off and I could actually hear music coming out of the final transformer!Thinking I have really gone and mis-wired something?
Anyone?

I've heard this a few times when running amps into dummy loads to break them in. After the break-in time, I connected speakers, and forgot all about it, of course.
I'm pretty sure I posted the same question here, or on the Bottlehead forum once, and I got pretty much the same answer...maybe even from Paul...eerie :)
It's not unusual. The transformer core responds to fluctuating magnetic fields, both through magnetic forces and through magnetostriction. Tightening the screws sometimes reduces the audibility.
Sometimes you can hear hum with the amp off and unplugged - picking up local magnetic fields from house wiring etc.
The amps were running but the speakers were off? How exactly are you doing that?

Stats - Unplugged with no charge (24hrs later) and also tried with no speakers attached to the amps, still hearing it.
If the trafo is vibrating that sound out of itself to my mind that would mean it ought to be introducing some distortion?
Audio Note iron too.
