Notes:
The original sound decoders were manufactured by Soundtraxx. Don notes that these boards had two tiny circuit-breakers that would be triggered any time more than 12 volts was applied to them, and they would require a reset by Soundtraxx.

This is the circuit board layout of the board that S-Helper Service installed in their F7 (only) models that were using the Soundtraxx Tsunami DCC decoder. This diagram shows how the various wires are to be connected. This version is for the models that have Mars lights.

This is the circuit board for the interface for the F7 where additional resistors were needed from the outputs of the Tsunami for powering S-Helper Service's 5-volt lights and LEDs. This was part #661-X002. This is for the version with the Mars lights.

This shows this board and the Tsunami installed in an F7. Note that the 5-volt lighting function of the QSI Revolution sound decoders (which were installed in later releases of this engine) made this interface board obsolete.
