When I was in big industry we would import machines from Europe and they

A bud returned from stint in Army in Germany with fancy new Dual

Yeah, but... at least the one I recall, there's a stepped shaft, you just
shift the idler to the 60 Hz step...

These used a rubber driver wheel. The fix is swap out a US motor and
idler but they were almost as pricey as the whole turntable. The GI
that unloaded it to him talked him into it by claiming the fine tune
speed knob could compensate...
