As most experimenters are aware high powered NSTs are slowly going away to 
be replaced by ground fault limiting devices built into the xmfr.  New PTs 
are very expensive and require external current limiting which is also 
expensive due to the high cost of suitable cores.

We have been working with and patiently waiting for a company to provide us 
with a replacement I designed nearly 1 yr. ago.  Finally, my patience has 
worn out as they are too busy to make small batch runs of coils for us to 
test --- this due to a new factory going up in China.

I am now working with 2 other companies, not as large, who seem to be 
interested in my project --- at least enough to provide us with some 'test" 
coils and cores.

Our goal is to have a working acceptable xmfr developing 16 kV (CT grounded 
like a neon) at 250 mA and current limited so an external reactor will not 
be requires.  A pair or trio of these connected in parallel could form the 
equivalent of a pole xmfr without the required external reactance.

It appears this might happen soon --- perhaps by the end of July or better.

A lot of experimenters have contacted me off-list and declared interest in 
this xmfr.  It hopefully will soon be a reality.  I trust by mid-July to 
have availability and pricing available to those experimenters.

Keep the faith,
