Toroidal Transformer for sale (free) / trade

skidave · 6th January 2009, 12:46 AM

I have a large Torodial Isolation Transformer that I no longer want. I save many transformers from equipment we dispose and I don't have a plan to use this one any time soon. It has multiple taps for 100, 115, 120, 200, 215, and 220 volts so it can be used for some step up/down ratios. The manufacture is Amveco Magnetics and it has a model number and rating sticker (705VA @ 120V, 675VA @ 220V). There is no wiring diagram, but I left the previous wires connected for a reference.

Unit is approximately 30 pounds and is 6 inches in diameter.

I don't want any money for the transformer (other than shipping costs). I'm looking for two decent 12BH7s (matched) for use in a preamp. I would like to trade if possible (yeah, I know...needle in a hay stack).

Here is a link:

If you are interested in working something out, please let me know.

I need a trafo with 60VCT and one with 70VCT. I can pay cash!

skidave · 6th January 2009, 03:42 PM

Sachi, I sent you two emails. Let me know if you get it.

Zero Cool, sorry...this was a one and only. It came out of a Boston Scientfic IVUS machine (that was about 8 years old). There are a ton of used medical equipment dealers that might have some laying around they want to part with.

Spasticteapot, sorry, nothing else at this time.
