Schematic attached...

Got them, Thanks, Looks like I'm going to need them. I cleaned the headphone
jack as starman suggested and now have very weak (very,very weak) audio at
both jacks. I suspect that someone has had this radio turned on with no load
across the output trying to get sound out of it with no speaker attached and
blown the chip. Oh well, guess I can't expect too much for $10.
Thanks again to Starman and the Maj for the assist, Rob Mills

Check the audio chip's output coupling capacitor, C63. It's an
electrolytic- 100mfd @ 16V. The chip is a UPC575C2, made by NEC and NAT.
It's still available from some surplus suppliers. Here's a company in
Ca. that can apparently supply it. Enter UPC575C2 in the search box and
choose 'closest match'. It shows thousands of them!
