torodial transformers?
 

i want to build a power supply for the sonic impact t-amp i have and because i want a sweet looking slim case (:D) a good torodial transformer would be cool. the thing is i heard that there are many "levels" of torodial transformers and most are not audio quality + i live in israel so it better be made in europe so shipping will be cheaper. i searched the forums i could not locate a good source. please help

Not sure if Ireland counts as close enough but you could try these guys out http://www.antrimtransformers.com/catalogue.php?sec=446 either their custom ones or one of their standard range. I just bought a standard range 300VA 2X 20V secondary, but havent used it yet. (I'm lucky there is an Antrim authorised manufacturer here in Sydney). I've heard good things about Antrim before and their pricing is good (at least here in Aus).

Hi,

I tried with Antrim last week, the trnsfo was 80 GBP, but the problem is that they charge additional 103 GBP for shipping (to Israel)!

yikes!!!! you might be better trying harbuch here in Australia... on an exchange rate basis would be better off for starters... I bought a 300VA dual 20V secondary for a bit under $70 a week or so ago, and that was a potted one, the non-potted is 7% cheaper...... don't know about the shipping but I would imagine a lot less than that!!!

Harbuch is licenced to make Antrim transformers.

edit: I think the base price without GST or potting was about $53 AUS, which is about 25 UK pounds!!!

you have a link maybe? i searched google and found nothing.

You can get pretty high quality transformers at Schuro:

I think prices are outstanding for what they are but ordering there can be a pain (like no reply or similar).
These transformers feature magnetic shielding, shielding between primary and secondary, special iron core, etc...
You want to build a separate power supply case?
In that case I´d use a standard toroid and nothing fancy/shielded/potted or so.
Don´t know what the T-amp can take voltagewise but I´d reckon a 9VAC/50VA would fit and be plenty IMO.

sorry here is the link :) http://www.users.bigpond.com/harbuch...ch/default.htm

I bought one of the standard range ones, but while I was there they said that they will do custom ones for audio, low flux density etc... I didn't enquire as to the price difference for a custom one though...

edit: the ex stock ones are cheaper too.... i was going to get a 225VA but it wasn't a stock item, the 300VA was and was $10 cheaper :).

monomonster,
You can get your transformer here in Israel if you know how to order for your needs,ie audio...
That`s not really a problem,
Contact me direct and i will tell you how to.
