@Boilermaker1 posted:Put 2 MTH resistors in the smoke unit, in parallel. You can solder them together under the PCB and stick 1 set of leads through the PCB to connect to the PS2 output. You don’t need the thermistor and you can cut the control circuit off. The circuit board just becomes a seal. Just drive it with the PS2 board. I did this along time ago with an atlas loco that had a TAS unit in it.
Do you recall what solder you used to solder them together. Is that unit still working today. Thank you,
