I'd like to use my UK stereo system in Canada which consists of amp (400w),cd player (80w), and subwoofer (50w).
Can I run all three from the one step up transformer, say 800w using a simple UK triple adaptor or extension?Any thoughts?

Check the wattage consumption on the back of the units. Then plug a UK extension cable into your ?? size transformer and plug that in the mains.

I hoped that was the case, a thought crossed my mind that maybe I'd need three transformersbut thankfull not

OK on the rating, but are these digital or good old fashioned solid state hifi units? If the latter beware of mains hum from the transformer.

Of course, it's a different kind of mains hum. Your 60Hz hum would be somwhere around B three octaves below middle C rather than between G and A flat at 50Hz. I'll get me coat...

i bought a step up transformer from Maplins prior to our arrival in july 07. its a 350w unit but powers my 600w stereo without any hassles (so far!) it does'nt hum at all!

It is a good old fashioned unit, so i'm fully expecting the "hum".....just have to turn the volume up then

Wont that just turn up the hum too? Its not just the physical noise from the transformer, its the electrical noise on the line too I suspect...

yep. I suspect adding in a transformer you may need to look at the earth circuit to avoid unnecessary loops that induce hum into the audio circuits

Certainly you'll want to make sure that the electrical field of the transformer doesn't encroach the amplifiers or other items

I think maybe I'll look into converting them to 110v.Anyone else did this?

Cheers

if you do it right the "isolating" transformer can reduce hum, if you don't then it can really give you a headache

I've done both routes, converted some units to 120v using small internal transformers which if your handy and there is enough space can be done easily but guarantees to void any warranty, but you do need to watch out for thing that use the mains frequency to clock certain chips, you’ll see this often as a circuit being pulled just before the rectifier diodes.
And I’ve used a 1kw transformer but made sure that my earth circuits were well managed (I had amplifier using balanced lines and an active crossover so not to difficult) mainly you need to keep leads to a minimum and make sure that they’re kept away from the transformer this is by far the easiest route but do make sure your circuit is earthed properly

Thanks for that Mike...gives me something to think about.It's a pretty good stereo, but if I sold it here, I'd probably get peanuts.

Not to hijack this post, how would you use a UK tv in Canada?
I have an upstepper for small things like mobiles, laptops and such..but no way will it support a plasma screen..

anyone ever done this or know how?
