U.S./ Canada Beofriends:
Does anyone have experience they'd be willing to share? I may purchase a Beolab created for the UK/European market, with a 220 - 230v, 50 - 60Hz power supply. It will require that I use a step-up transformer here in the U.S.
Anyone with a similar situation? Does your transformer deliver reliable power? Sixty-cycle hum, or get hot, or...? Recommendations or problems?
TIA
Pending what you are purchasing, the beolab in most cases can be rewired inside the beolab for 110 volt, on the powersupply board.
I used converter for my BL2500 and Beosound 2300.
Technically there was no issue, No hum, no heat. I bought 3 converter at radio shack back then.
Just note that there are different types of these converter, for hair dryver, shaver they are dirt cheap and would not work for your device. For electronics they typically have much less output and are more expensive which is why I ended up with 3.

Excellent, great to hear. (Or not hear.)

I'm not sure that I understand. What is '3 converter?' I assumed that I'd need a fairly beefy step-up transformer, in the neighborhood of 500W, such as this one on Amazon.
On BL 2 which was actually the first real ICE-power loadspeaker from B&O giving an output of 850 watt, it was not possible to rewire the power supply. Both the transformer and the PSU board had to be changed.The max power consumption on the BL 2 for a 850 Watt output is 70 watt.A thumrole says that the transformer should be 50 % higher. So a 100 watt transformer will do.No hum or his will occur, due to the fact that the BL 2 power supply will filter off all noise.It's nerver mind for the BL 2 if the frq is 50 or 60 hz .
Super-helpful, Fritz, thanks.
Besound 2300 and pair of BL2500 needed each their own converter since they were drawing so much power. Initially I was thinking 1 is fine. cheers
It doesnt open the amazon link for me, but most higher rated converter are for appliances not electronics. Mine were just rated for 40 watts each but they were regulated and speficially for electronics, not appliances.
cheers

A little info:Beocenter 2300 uses 30 watt, and each BL 2500 (a class AB amp) uses max 100 watt each.Therefore three trafoes were nedded.However both BC 2300 and BL 2500 can be rewired for 110 volt.
