Hz AM/FM

Guys, gals
I fiitted out a yacht with 120ac 60hz, put on all the top gear, the new owners are in a 230 vac 50hz place, they chucked out the expensive Denons and gave em to me
I can step up Volts but making a HZ converter is expensive
Will running these radios on 50 Hz kill em in long run, Electric motors are happy enuff, they just lose a few rpm,
thanks

Old Norwegian mercant sailers often brough home radios from the US.

They normaly worked ok, but the LP players was running a litle slow resultin in Love me thender lasted 30sec extra

Atleast that is the storys I was told when I grew up and I was also told there where modefyed to runn normal speed.

Maybe electric components 30years ago could handle it bether than the one today

Lazyjack, what does the nameplate say for voltage/Frequency??

It is likely that any 120V 60 Hz radio will work OK on 120V 50Hz.

The unit's internal power supply will usually step down and rectify the input power anyway, the internal electronics usually require DC power at or around 5, 12 and/or 15 V. Apart from a less efficient rectification and probably a little more ripple, I can't see any huge reasons why a 20% frequency variation would be a huge problem on a device with an internal, regulated power supply. For something that doesn't have internal power filters you might have trouble.

thanks all, I went all the way to Seattle to get all this stuff, inc the trace sine wave invertor, which has had to run 6 years cos its on 120, , there is no 120 shore in,in Aust. so we run off 900amp hour bank,, the bank is charged by a smartcharger that runs any VAC AND Hz,and or by the race through the genset at sea or buy the big dc alt on the main eng. i NEVER REALISED THAT dENON DO MAKE DUEL VOLTAGE STUFF, when it gets delivered on Saturday I will have more idea
the Moorings Co. down in BVI told me there would be a great market for portable frequency /voltage converters down there So theres an opening for someone
cheers Stu
