Hi All,
gone through some older posts referring to that pronlem:
it is apparently not recommended to use a step-down transformer running a 120VAC/60Hz transformer at 240VAC/50Hz because the bipolar capacitor is different and could cause incorrect phasing for the motor circuit apart from perhaps other issues ?
4C1 = 27uF for the 120V/60Hz , 4C1 = 39uF for the 240V/50Hz version.
if my step-down transformer supplies the correct tap voltage for the 120V/60Hz transformer could I partially counteract the frequency problem in changing to the cap used to the one with 50Hz mains frequency ?
meaning, still using the step-down transformer but replacing the 27uF cap with a 39uF cap ??
Thank you so much for your adviceš¤©

Yes.And ideally, you should also replace the rear carriage rail. It's different too.

thanks Martin,
changing the rear carriage rail will probably prove to be more difficult than changing the capacitor. ?
see what I can do.
best solution would of course be finding the Mains-correct transformer ?!

I agree.
