Anyone know where you can get smsoke unity parts for the S2 Turbine .  I need the circuit board to which the smoke unit is attached by wire.  Part Number 1023-x004.  Williams parts no longer carries smoke unit components.  This board looks similar to the resister board which Williams does carry but is sold out of.  Maybe it is the resister board I need but the parts number does not match that on the board in the engine.
