Default Odd radio sound coming from Alps upgraded volume pot

Viktor,

I hope all is well with you!

If I touch my volume knob and keep a finger on it for a second, I pickup the sound of an AM Radio station and also a slight (very faint) static-pop noise when the finger is placed and sometimes lifted from the volume knob.

Is there something I can do to eliminate this?

I'd also be curious as how I could remove the volume potentimeter from the unit altogether. I wouldn't mind converting the unit to a power amp.

Very simple---> you do not have good grounding.
You need to sand the volume pot washer area . Please look at step 5
