[sdiy] EMS VCS3 VCO

[Yves Usson]

Hi and happy new year !

I intend to build myself a clone of the EMS-VCS3 and before going into
the hardware, I tried to simulate the behaviour of the VCO1
with Spice3. The simulation is based on the schematics available at
Graham Hinton's site. Unfortunately, the bloody thing doesn't oscillate 
at all ! 

Has somebody in the list ran such Spice simulation for the same circuit
and did it work ? Has somebody built the oscillator from this schematic
and what are the pitfalls?

Thanks for you advices.
