MTH Z-4000 powering Lionel powermaster - no sound on Proto one - why ?

model A guyOGR Forum Member

Trying to run MTH proto one and older Lionel conventional engines with Lionel powermaster in conventional mode while using MTH Z4000. Control is responsive and operates very well, however, sound is no longer there on all MTH engines I tried.

I know that the proto one engines require a pure sine wave AC power and I am supplying that with the MTH Z4000. I can only assume that the 135 watt original Lionel powermaster must be chopping the sine wave.

Has anyone ever opened up an older Lionel powermaster to see if the circuit can be modified ?

Does anyone have a fix or ideas how to make it work with the original sound ?

Does anyone know of a remote control that can alter the AC current somewhat like the Cab-1 and Lionel Powermaster to control conventional locomotives ?

I'm surprised I could not find a thread about this
