Sony ICF-9650W Volume Issue.

[awolff01]

This may need to go in the DIY forum but I figured I try here first.

I have the above radio. Great condition. The volume control knob when turned makes a very loud static"ky" sound but the volume itself does not seem to get any louder.

I was told I might need to replace the potentiometer. My question now is how do I find out what potentiometer to get?

Where can I get schematics for this radio?

Thank you all.
