PT-25 audio distortion
#21

If you suspect the pot, then find a station that is received well enough to be heard well but not too loud at say half pot scale, disconect the pot, and connect two resistors, one between the low point and wiper being, say 50K and the othe between the wiper and the top point being 450K (values are approximate, don't have to be exact) and see if the distortion persists.
I doubt it, but possible.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
