?I found my corsair II to pick up a hum/buzz if the supply is close to the rig ,moved it 3 feet away and all seems ok now. That was a 961? tt supply. Maybe comming from a source in your house?

I've got a Corsair II I'm planning on recapping with Ultra Low ESR 
electrolytics. There's a high pitched buzz I can hear which is 
distracting somewhat but is mostly absent when the narrow filters are 
engaged.

It was there when I sent it to the factory for repair several years 
ago and they found no problems but I notice it and it was not there 
on my Omni and is not there on my other radio (not a Corsair).

Any suggestions of which board I might start replacing the caps on to 
eliminate this noise?

Thanks!
