Can anyone help me out with a problem I'm having with my PM-66SE. The input fuse to the transformer keeps blowing. Each time I replace the fuse, the amp will work fine for a day or two before blowing again. Usually when I turn the unit on. Any Ideas?
If the transformer is a toroid, look for an inrush limiting circuit. Check if it works.
Also check the main psu capacitors haven't gone faulty and are drawing excess current.
