Step Up Transformer 100v

Thanks for the reply. I would like further details but I think I'm looking for something simpler. Maybe this unit will be good for my purposes:

The Electro-Harmonix EHU600 is the only step up transformer I have come across with a three pin socket for earth. Thanks!

The EHU600 is limited to 600W. Find the maximum draw of what you want to plug into that and double it. 600W is small for an amp. unless it's a flea watt.

I think BigShutterBug is referring to these:

And this is an enclosure that can fit up to the 2KVA model.

OK, thank you for the links. My amp - NaimUniti - is only rated at 50w. This could change in the near future to 80w. But I think the EHU600 is suitable for these ratings? Thanks!

Max power consumption for that Naim is rated as 350W but, being class B, it'll want that faster than you can say ,"Now!", to recharge capacitors.

Someone at Naim told me I'd need a 500v step up transformer, so I thought I'd be OK with the EHU600. Am I wrong, however?
Thanks!
