110V/50Hz equipment in a 220V/60Hz country.

What has been said above is largely close to the experiences I have made. I live in Europe and I am using Spectral equipment of 120VAC provenience. I feed the preamp, as well as other audio gear through a PS Audio 600, which is set to input 230VAC and will output US voltage. For the big amps I am using Equitechs (www.equitech.com) of sufficient wattage, which will also use 230VAC at their input, but deliver 120VAC at their output, with the added advanage of balancing the output, which means about 6db less noise in the powerline. (The Spectral Monoblocks cannot be inernally converted to a voltage different to what they were made for.)

I am in Australia (240v/50Hz), and have had some experience with your dilemma. With most US made equipment, changing to a different voltage has been thought of in the original design. Some make it extremely easy (I have a Rowland preamp with dip switches for different voltages), some fairly easy (e.g. Pass Aleph 3 required a jumper resoldering), a few will require a new internal transformer (if you dont want to use an external one). Almost every company I have asked will respond to questions about how to reconfigure their equipment. The rare exception being Spectral. I use a Spectral power amp through an external stepdown transformer without any problem. I am unable to say if the sound is degraded, but I am happy with it. Any equipment made in a 220/240v country is more likely to be easily changed (e.g. Plinius, YBA amps)

Thank you all for the responses.
Most of them have focused on the power amp,
I must admit I am just as worried about the CD and tape
player. Can the change in frequency affect the operation?
(this may be a very naive question, but anyway.)

Cheers, and thanks,

Hi Vas, some (rotor) motors depend heavily on cycles to keep the right speed (TTs, cdp's & tape players use motors). So, IMO you're best converting these machines to EU (if that's where you're headed!) standard 230/50. Surely manufacturers can oblige when the time comes... I shouldn't worry -- or am I too optmistic?

Cheers!

Motors in cdp and tape decks are dc motors so frequency change does not have any impact. However, TT motors tend to be ac and frequency change will affect its operation.
