I'm helping my grandson with an HO layout. We got a Walthers turntable installed with a motorizing kit that require 12 volts max. He's got a power unit to run the train but the auxiliary output is rated at 15 volts. We also need a rheostat of some kind to operate the table?
We also have two Atlas # 65 undertable switch machines mounted and the proper momentary control boxes for it but the instructions do not give a voltage range.
