Default 1kVA Isolation Transformer Beautiful

Check this out on EBAY!
http://cgi.ebay.com/ws/eBayISAPI.dll...m=330308625202
This deal is FANTASTIC.
Its a 120VAC to 115VAC toroid. Beautiful from the pics. Amperage is 8.25 and VA is 948.75 - his words.
Really? Could you ask for a better Isolation Transformer!
He wants $20 each and about 15 shipping in the US. Transformers like this at ANTEK sell for over $100.
Bump this article if you read it since no one is going to respond to this post so it doesnt get lost while his supplies last!!

I am new at this (like less than a month DIY) ... would you use this to decouple your house mains? so in a sense this is a filter?

Sorry, new at transformers.

Could you wire the primaries in series so that there's 60 VAC across each pair of primaries (tie white and gray together) and 57.5 across the output?

Then from that wire use center tap to do 28-0-28 VAC?

Thank!
Justin

Great page to start with. Read about Isolation Transformers. If you are using this for your amp then I think you will get by with one of these because the isolating will happen between this transformer and your amps power supply transformer. But I dont think you would want to take just one of these and feed your TV with it. I think you would buy two and put them back to back THEN feed your TV or anything else with it for that matter.

I have no idea. Sorry. Not a transformer expert just noticed this very good deal and thought you all might want to see it.

cool I just bought one .... not sure what i'll use it for but I got one .... I am in the parts collecting phase on the hobby ... would you use this on an amp build? would it really serve a purpose ? and that and two trafos in the same case... it would be a huge (and heavy) case.

This trafo would best be served for building a nice isolation system for your sources and preamp. Would also be perfect for the diy 'geddon turntable supply.
