Love my vintage Sanyo Plus series.

Looking for another if you have one



re: Plus P55

This is an absolutely fantastic amp!
Unfortunately not so reliable.
In mine both power switch and many solder joints on the power fet boards had failed.

re: Plus P55

I loved my unit for years. I am now having issues with it. I wonder if you know of any online repair places that you could supply me with.
