X-101-C Phono Section Is Squealing Badly

It worked perfectly fine last night for the hour that I was using it.

Today it is passing no audio from the turntable from either phono 1 or 2. It is only making that awful noise.

The first thing I did was swapped out the tubes with a good set. It made no difference.

The other channels still work normally.

I’m looking under the hood, and there are no obvious signs of trouble. Everything appears normal.

Glad you found it! I was going to suggest just what you did. I have an X-101-C too and as part of the restoration I had to clean the function switches plus the slide switches. It had sat for a long time in a very humid environment.

Thanks. Me too! I had cleaned all of the switches and pots about 6 months ago at the time of the rebuild, and thought that it was going to be a much bigger problem.
