When dealing with open frame AC motors, current draw is significantly higher. Deciders should be rated for stall current of both motors not operating current

Matt,
I have a couple old 2343 f3`s, do you think a 5 amp decoder is big enough for those old dual moter locomotives?
I was the first O scale trolley guy to go dcc back in thw early 1990`s. I had some old freight moytors with big pittman motors and the 4 amp decoders Digitrax had back then could not handle the load and I smoked more than one. They were a lot more than $66 back then. Maybe it would be better to use dcs or tmcc?
Thanks
Mike

Tmcc would work, but no availability for the moment. DCS would not work because it requires a flywheel for the speed control. Unless the motors are cans already, you would have to remotor the locos if you wanted to use DCS.
