They ask $500. I didn't check the code, but I guess you can read it from a pic. It's 4 x 30V.

If you can unwind from your secondaries to get to 60-0-60, you can make a nice isolation transformer. If you ground the center tap, you can use it for your front end in balanced AC power setup. If you don't know much about it, ask Coulomb, he got me interested in that.

Did you buy that or do you just have the pic? I have a huge industrial power supply that I know nothing about. It is made by a company called lumax (whatever). No one would want to pay for the shipping, but I am often in the Milton-Burlington area if anyone is close. I will post pics tomarrow

The big Plitron is on loan from a dealer. I wanted to try it for balanced power operation, but somehow didn't have a chance to do it yet. If you have a big trafo you want to get rid of, post a pic and I might be interested. I'm located in Mississauga.

Geez you guys, the guy is offering a free trafo take it or leave it! It looks to be a ~500VA by the way.

Peter,
that is definitely too big to be a 1500VA. Over a half of that is for shielding and potting. I bet you are never going to have a problem with stray EM's from that bad boy. The shield-less 1500 VA they are selling in the surplus area has a form factor which is very different from that and it's about 8.5 in diam. x 3.5 height.
