And speculation it is. I have the full schematic and it is so simple it
nearly made me cry. Only the lower section has a 3900. The rest of it is
3080s and dual op-amps. The middle section is basically a series of
differential amplifiers with parallel diodes in place of the resistor to
ground. The two inputs of each diff amp are connected together.
I built a clone, and it does indeed sound very good. If a little
unusual.
