Where to buy transformers

SupraGuy · 9th September 2004, 01:24 AM

Perhaps it's my search skills, but I wasn't able to come up with any useful or definitive information on this.

Canadian vendors would be preffered, so that I don't have to worry as much about border costs, however, it's really not that big a deal.

I'm looking for something with a 110V primary, and a 25-0-25 (or 50V center tapped) secondary, 200-300 VA range. I don't really care if it's torroidal or EI or other, as long as it'll supply the power that I want.

Again, maybe it's my search skills, but I can't find anything of use on Digikey's website...

If you can use a 100Va at $17.95ea I have
Avel-Lindberg 2 X 25 Volts, also a 2 X 28.4V
at 160Va for $22.00.... However I'm in California
and will ship to Canada........

If Apex doesn't quite work for you, try Plitron, located in Toronto. Excellent reputation and product.

Hmmm 100VA is a bit on the small side. I suppose that I could use 2 of them with the secondaries in parallel, but I was hoping to have a bit less bulk in the power supply. It also increases my part-count, as I'd need 2 bridges, and more filter caps as well.

I'll give plitron a try, to see what their prices are like in the size that I'm looking for.

Thanks for the suggestions!

Edit: OMG

A 225VA 25-0-25 transformer would cost nearly $80 CAD. I'm sure that I could go to a surplus store and buy the whole <expletive deleted> amp for that much! I realise that DIY doesn't necessarily save money, but this is ridiculous! Next to that, a couple of 100VA transformers at $22 USD each out of California doesn't seem so unreasonable...

Where are you located?

Go your your local surplus electronics store and do some searching.

Or find dead audio equipment from friends, garbages, etc. :P

Even odd equipment often has some decent transformers, somebody was mentioning one they took out of an Apple printer.

More recent products willl usually have cheap low rated transformers though.

Avel Lindberg sell direct by phone. Go to there website (search for yourself, I'm too lazy to put a link) and pick one out. They sell many voltages and up to 1000va for about 1/3 the price of Piltron.

Ah, but they're located in Conneticut or something

Parts express carries them up to 800va for $70 each
