  Could you possibly mean the power transformer?

    Yes, that's correct. Here's a picture.

      Are you sure the power transformer is bad? The nice about having a solid state unit's power transformer out is,they are much easier to find a workable replacement because you don't need filament or bias taps as you do for a tube unit.It may not be the same style but it can fit in there and work just fine.

        I'm reasonably sure. I took the power supply a friend who helped me check it. He could not find anything wrong in the DC circuit so he checked the transformer. He measured on 10 ohms on the primary input and told me it should be in the 250 to 500 ohm range.

          It keeps blowing the 600mA fuse too.

          Can you email me the schematic at merccougar89@gmail.com 2 ohms to 10 ohms is ideal on a tube amp's power trafo but this is a sold state radio..Radio Museum has one but I lost my password.I need to see what the circuit looks like.
