Waallll, this is a very interesting situation here...(spoken in my best Jimmy Stewart drawl)
I removed the shield from the function switch and cleaned it, letting it dry out for a little bit before trying it out again.
The static returned after about five minutes of playing - first in the left channel only, then in both.
I had left it right side up so I could check the outputs of the AM and FM boards.
Both were clean, no static.
I then turned it upside down again and retraced the signal.
The sound was clean at the volume control...but the static was present at the input to the W15-079 control amp board. The static was much louder, of course, at the output of the control amp.
So now I am wondering...could the control amp be the originator of the static, and is it severe enough to make it reflect at the inputs of this amp (yet not show up at the volume control)?
Forgot to mention...tapping on various components made no difference.
