Minimoog Vcf

[Steven Cook]

Hi,

I've built the Minimoog vcf from the "minifilt.gif" schematic available on the
Music Machines site and others and it doesn't work! Nothing does first time,
but I can't find anything wrong.

The ladder network part works fine, as I have tested it using another
differential amp circuit, but the output amp is dead.

Has anyone built this circuit successfully or does anyone know if the
schematic is correct?

Thanks,

Steve.
