Default Re: Trio 9R-59D receiver problems.

I think the hum may be from the mains transformer .So i removed all 4 of the screws so as to let the laminations [i know all about these i used to make them ] open up .Thats if there is any gaps . Next step will be to varnish the joints if any .Then clamp it back up ..
