FWIW, the resistor in the HO unit is 16 ohms.
I think maybe the second one, the AA-2100002 I mentioned will give you more smoke if that's the goal, and it's not much larger.
Here's a comparison of the two.
The title was HO in O gauge so I assume, plus someone else was asking me via e-mail.
For MTH O when they use the single element version the board is a flash board with a different smoke output to prevent burning up the element. Hence my warning. Certainly if modified and current limited based on how you are powering it, it can be made to work. G
