Voltage conversion from 220V to 110V.

With all the deals you see on Euro and Asian market stuff that operates on 220V its hard not to wonder is there a problem using a North American converter.

Ive got my eye on a set of Asian market mono bolck tube amps. Theyre the 220V version but theyre also about $1500 cheaper than their North American counterparts.

Can I expect any sonic problem stepping the voltage up for their requirements with a high quality converter?

What kind of converter would work best?

Thanks.

A "separate dedicated 220 volt line" is not a big deal. Your clothes dryer, stove, and maybe your air conditioner and hot water heater all run on 220.

Actually, most electronic equipment is easily changed to use 110 or 220 (sometimes as easy as a switch or plug-in jumper).

If you need to hire an electrician the US model might be best.

I believe the 220 line will be a little "cleaner" than the 110. And the cost ($300 approx) of having an electrician install a dedicated one for you, depending on the length and difficulty of the "run", will probably be a fraction (20%)of the difference of cost, between the 110 & 220 models.
Good luck and good listening!

You may want to check with the manufacture of the Amps to see if they are dual voltage via way of a switch or internal tap change.If they are not,ask them about using 220\230 volt USA power.If the Amps are 220v 50 cycle only, I would ask if 60 cycle is ok.You may have more heat because of the difference in frequency.Make sure the power transformer winding insulation is capable of the extra heat if any.cover your bases before you buy.

Jea48...Why would heat be different for 50Hz and 60Hz AC power? Both would have the same RMS value.

I think that 50 Hz would theoretically require more capacitance in the power supply filter, because the ripple would be at a lower frequency. But I bet the difference is trivial.

dont worry about the cycle with the amp. is very important for digital(home theater only) not for analogue.
