Interesting. Maybe there was a non-VCA version of the CR module that was originally fitted to your desk. You can quickly generate an almost +/-10v signal by clipping two very new 9 volt batteries together so the + of the 1st clips into the - of the 2nd. That centre connection (where they clip together) will be your 0v point while each of the exposed contacts will be either + or - 9.xx volts, depending on which contact it is. No idea if that will provide enough voltage and current for the VCA's, but it's a quick and easy test...
Best,
