That's a ferroresonat transformer IIRC (why, I have no idea, there are 
conventioal electronic regulator circuits in the PSU too). There could be 
considerable stray field from that.

I still suspect the spindle motors of the RC02 first, but I've got no 
real evidence for that.

Jay, can you rearrange the items in your rack to move the RX02 and RL02 
apart?
