Hello,

I have an old Hallicrafters s-120 (made in 1966). I have been having trouble
with the volume control. Everytime that I turn the volume on about 1/8 way
there is a very high squealing coming out of the speaker. The question I am
asking is: What could be causing this problem? I've been told it's either
the speaker or the potentiometer. Any ideas?

Thanks for any input,
Bruno Hache
