Re: [TCML] 12 kV Potential Transformer on eBay for less that $100

Good job, Charles. I was hoping someone from this illustrious group would hop on that. Actually, there isn't as much competition for those big and heavy high voltage, iron cored transformers (or the big commercial high voltage pulse caps) these days amongst the coiling enthusiasts as there was 15 to 20 years ago. Most of the newer generation of coilers are all about the DRSSTCs and have little interest in the "stone-age technology" of spark gap driven coils, and most of us older coilers have already scored more items of this nature over the years than we know what to do with. Still, it seems that nowadays, most of the eBay vendors have done figured out what those higher voltage PTs are actually worth from review of their starting or buy-it-now pricing.

Bert thanks for the heads up.  I got up early this morning and noticed no
one had bid on the transformer.  Got it for the starting bid.  Ans I do
have an idea for its use.  I have a real old x-ray rotary rectifier setup
that I might modify to use as a charging/discharging arrangement like in my 
DC coils but operating with an ac power source.  Hopefully I can make it
work.  Charles Rakes

I just happened to stumble upon a good deal on eBay for a 100:1, 1500 VA,
12 kV potential transformer, located near Kansas City, MO. The offer price 
(no bids as yet) is $97, or about a buck a pound. These devices typically
go for $1000 - $1500 on the surplus market. Specs can be seen here:
