Default Simple Variac Question

I'm having a little hard time finding a 1:1 Center tapped transformer with
some good power.

Hammond makes an 80CT transformer @ 4 amps
http://www.hammondmfg.com/165.htm - 165N80
but that would only give me 40VAC each tap, but pleny of current. Maybe
that's all I'd need, I don't know.

I think their 300 series would be a little under-powered.
http://www.hammondmfg.com/300series.htm - or am I reading the specs wrong?

I've been doing searches on google (and on ebay) but it seems finding a 1:1
center tapped transformer with plenty of power is hard. unless maybe I'm
not looking in the right place.

Just looking for a little help.

Thanks!

Matt

It is NOT a transformer. = NO isolation.




Well it is a transformer, it's just one that has one side of the secondary
tied directly to one side of the primary, hence no isolation.

You can get cheap 1:1 isolation transformers, they're sold for use with
older video arcade monitors. Any place that sells amusement supplies
should have them. I get most of my parts here

Not sure offhand what current the transformers are good for, but usually a
few amps.
