Since it has a strobe, it will have an adjuster. If it had a synchronous motor you would have had to change a pulley size. You can always make a strobe disk to suit 50Hz to sit on the turntable, or you could get someone to make a little strobe light operating at 120Hz - that would have pose value!

I ran an American Garrard deck in the UK for several years using a mains light bulb in SERIES with the motor. It glowed dimly and was only slightly warm - it was mounted inside the box. It's cheap and very easy to do, but you need to know what you are doing. You could have it outside in a nice desk lamp and make a feature of it! It's also possible to use a lamp dimming type circuit but they tend to be electronically noisy and may give you grief in the audio department.

Do a search on this forum and you will find an LED strobe I designed. It can do 50Hz or 60Hz depending on crystal choice.

I couldn't seem to find it either, so here's the circuit again.

FYI, with Lenco turntables, you can't move them across the pond- having a different mains frequency (50 v 60 Hz) causes the spindle to turn at a different speed (or something like that - the idler arm runs off the spindle?). I don't know if this will be a problem with your turntable, but maybe someone else does...

The motor pulley on the Lenco is replaceable for 50/60Hz operation. Hard though to get the part these days I'd imagine.
