Krell KSA-200 Problems, Caps Etc.

Hi there I just bought a Krell KSA-200 and it needs to be fixed. It is making cap noise and the heatsinks are much hotter on the left side than the right. Also the middle right heatsink is just a bit hotter than the outer right heatsinks.

The heatsinks arent purple so it hasnt been over heated. The amp had been sitting for a few years and was just turned on. The problem could have been before or after he had turned it on recently.

I want to keep this amp, Fix it and make it close to new. It should be less than the cost of my current amps and should be a very nice upgrade to power my new wilson sophias.

Does anyone know any typical standard issues that these original KSA Amps have? These were the one before the S series.

Thanks

Toby
