66.30.62.12
I'm considering rehabilitating my 1980s Thorens TD166ii, which has a 50 Hz 240 V motor.
The AT31E cart (10 Ω internal, spec'd for >100 Ω load) should work well with 1:20 step up using LL9226 without needing parallel resistor.
But can you suggest a way to power the motor that doesn't involve audiophile pricing? I'll be running it in the USA so a transformer won't be enough. I'll need a 240 V, 50 Hz AC generator for a synchronous motor rated at 2.5 W.
Follow Ups:
Autotransformers specifically intended for the 120/240 issue are available. You deal with the 50 Hz. vs. 60 Hz. issue by changing a pulley.
A motor/generator set is definitely not needed.

Thanks Eli!
I hadn't thought of changing the pulley. That's a much better idea. I prefer simple solutions.

A different pulley corrects the line frequency issue (and consequently the speed), but not the voltage.
