PT-25 audio distortion
#2

If you have the schematic, post a link or the image. Nostalgiaair does not have it even though it does have PT-25 entry.

Distortion could be a result of some wrong voltages, possibly due to bad resistors.

But then those radios do not have too many resistors so why don't you just go through them. If the radio is AC/DC (or just transformerless) and there is a input RC filter after the rectifier, see if the large resistors there are ok.

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.
