A/F Hudson smoke unit

Charles, The first question I have is what is the resistance of the smoke resistor that you installed, Gilbert smoke units were generally set around 35 to 40 ohms. A resistor in line with the smoke unit would need to be quite high wattage or it will just burn out. Might you be able to find a higher resistance resistor to install in the smoke unit?

Thanks for getting back to me Ray. The resistor installed is the original Gilbert type and I always test them post installation to make sure they're between 30 to 40 ohms. I did experiment once putting a Lionel type resistor in a AF steamer and it worked fairly well, about the same smoke output as a Lionel post war fluid type unit. I think I'm going to take your advice and try that, thanks!

I'd suggest rewinding the smoke unit element to a higher resistance.  AF units are typically 35-52 ohms depending on whether 4-wire or 5-wire and desired level of smoke volume output and/or coil longevity.

+1 on rewinding.  Thats the simplest way to do it, and it would likely work better anyway.
