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!!

You are on the right track. There is one in my power conditioner.

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.

Right. Thats why I suggested buying two and putting them back to back. This will give you the isolation you need. I am going to give this

a go and see if I can get rid of some noise I have on my AC lines. If it doesnt do the trick I will buy one of these transformers and put it in back of said circuit and see if that does it. If not I will, phew, get one more and do the back to back deal.

Hey guys,
I've got a few 1.5kVA E type Isolation transformers available. I don't have a set price, but I am willing to trade or review any reasonable offers.
If someone out there is knowledgeable enough to put together a rock solid power conditioner schematic, perhaps we could trade knowledge for Iron/copper.

Ryan,
As I mentioned above, I got a powervar silly cheap. I could take a look at it and get a better schematic, but essentially it just goes from AC input to AC output (with input ground and a ground from the trafo) and then runs through a few red drop capacitors and then to 6 AC outlets. Nothing really fancy, except the red drop caps.

I know this an old thread...
I bought two of these transformers (thanks for the suggestion) and just now I am starting to build a variable-isolated-AC power supply for my bench.
This will be (at start) nothing more than a variac followed by an isolation transformer. Latter I will add an ac-dc portion and a PIC controlled volt-amp meter.
Since I lost all the information on these transformers, I wonder if you still have it.
There are 4 wires on one side (white-blue-black-grey) and 3 wires (red-orange-red) on the other.
I am assuming that there are two 110V winding on the 4-wire side and a 0-110V-220 winding on the 3-wire side.
Does that sound about right?
I appreciate any information you can provide.
Cheers!
