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!

Many thanks again, I'll do all of the above. Rob Mills
