Default Marantz Pm-66SE

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.

Hi geddam,
Is it possible you put a fast blow fuse in where there was a slow blow fuse? That would do what you are seeing.
