CEM-circuit engineered for music

>Had to canibalise a perfectly good HC-2 handclapper for a BA662 to
replace dead vca in
one of the voices.

The BA662 is still available from Roland, at least in the UK. Price is
about 4-00UKP plus handling charge. However, any OTA will do the trick
if you are going to trash the pcb. My favourite is the CA3080, because
it is cheap.
