Nope, this radio looked nearly new. Don't think these HP40W's have been around all that long anyhow. Did get around to looking at the pots a little closer, black powdery and comes off easily on your fingers. Didn't do any more investigation and trashed them. Puzzles me, really looked like they were just made that way and not really any burnt smell coming from them. Anyhow, they are long gone. If I ever see another one like this it would really prompt me to investigate a little further! Me thinks just factory defective pots that didn't have the resistor carbon path baked on correctly? Never seen such before nor seen the manufacturing process of these little pots but really do suspect they were just not made right in the first place. I am not knowledgeable in potentiometer manufacturing but my guess is that these parts skipped a finishing process at the manufacturer. Might seem like a far fetched explanation but is as good a guess as I can come up with now.
