Default Russian Clock Radio on Our Voltage

This forum was as close as I could find to my question.
I am looking at this item on ebay right now and I am curious as to what I would need to do for power.It runs on 220 50 hz
https://www.ebay.com/itm/ELEKTRONIKA....c100752.m1982
I know a transformer would fix the 220 problem but the 50 hz? Not sure about.Never dealt with a different Hz before.I am just casualy interested in getting a old radio and perhaps something like this digital clock from over in that part of the world .Would be a neat conversation peice.

A variable frequency drive (VFD) can make 50 HZ. 220V should be available in your home without a transformer, just need to run a circuit for the clock.

of course usa is 60 hzs. that means 60 cycles per second (north, south) pos neg, electric equipment is designed to run 10% above or be low rated power approx....

It would depend if the clock uses the line frequency as it's time base or not. It very well may. In that case it would run 6/5 normal speed on 60 cycles. Running it from a VFD would then give time keeping that is only as acurrate as the VFD's time base, which you would probably find unsatisfactory.

Or it may be independent of the line frequency. In that case, it likely would run just fine on 220 volts, 60 cycles.

From what I am reading here, it may not really be feeseable for me to get 1 as I do not have a VFD and was kinda hoping it could just work along side some of my old radios with a transformer to stepup the voltage. I am hoping to get back to fiddling with my old radios.I have kinda let them gather to much dust and yea I have a old clock but since I like strange stuff, I thought a russian clock and or radio would be a neat addition to the collection.

I agree, probably 6/5 fast, but I wonder if the old Soviet power grid was as stable as ours. If not, maybe this alarm clock has a crystal time standard, and would still be useful at 240v/60 Hz. Just a thought.

Likely has a crystal reference in it and will work just fine.
