I've been offered an old kenwood DD turntable for next to nothing. No idea what model as I have yet to see it but I understand that it is designed to run of 110V AC.
Is it possible to adapt it to run off 240V AC by just replacing the mains transformer or is it more complicated than that? |

I think the easiest thing to do is use a 240 to 110 volt step down transformer.

You may be able to find a suitable replacement mains transformer or just use an auto-transformer to step down the 240V to 120V.. If the table has a stroboscope for 60Hz only (unlikely) you may have a little trouble setting speeds..

Yes, a step-down transformer seems the easiest way forward, (I hadn't even thought of that that option!).
From what I recall it does have a strobe ring on the outside of the platter. Is there any way I can get this to work in the UK? Seems as a shame not to be able to use the strobe . ![]() |

I've just come off the 'phone from the current owner of said turntable and he informs me it's a 3070.
He just want's shot of it as he cannot use it due to the 110V AC configuration. I figure it would be worth having a play with so I think I'll buy it and see what happens. |

Some (most?) turntables that use a line-powered neon strobe have two sets of markings on the platter for 50 and 60 Hz operation.

Hi,
count how many times it turns in three minutes. 100T+-0.25T should be good enough. Forget the strobe. It changes with the mains frequency.
