What is needed to hook up a smoke unit to a ERR AC commander to a postwar 2055? Will the commander power the postwar smoke unit? Any help will be appreciated.

The "feature" output on the AC Commander is powered by a triac which can overheat if connected directly to a postwar smoke element having a resistance of about 16 to 18 Ohms. To avoid potential damage to your AC Commander, I would recommend modifying the smoke unit. Liquid smoke unit upgrade kits are readily available from parts vendors like the Train Tender, and they typically have a higher smoke element resistance. Be sure to check before buying. Others have recommended elements with a resistance of no less than 20 Ohms to avoid overheating problems.
Thanks to all
the Train tender is ????
Would a 27 Ohm unit perform OK ?
