Prior to using MMC's and Maxwells, I also used a Fair Radio cap.  I was 
always pleased with the performance and saw no obvious improvement when I 
upgraded to MMC's and Maxwells.  And like you, I also noted that they get 
warm rather quickly, so I never permitted extended runs.

These caps have been discussed exhaustively on this List, and the consensus 
was that they have Mylar dielectrics.  This was determined by a decoding of 
their part number, but they were made by a now-defunct manufacturer.

Hello all,

Back in (I believe) 1999, I bought some 100KV caps from Fair Radio
Sales.  These came out of an old government project which used 100 in
series.  Markings are F-C-I, KM14-1000-10, .01MFD-100KVDC, NOV
1983.  Dimensions are 10X5X2.5" with two copper 1/4X1" threaded studs, one
on each end.  There is also a nylon screw in one end.  Case seems to be a
white PVC.  I used two of them in the coil I had at the Cheesehead
Teslathon.  They seem to work well for TC use, although one seems to be
getting a hot spot, when used with my static gaps, with the rotory, no warming.

Has anyone else gotten their hands on these, or have had a failure with
these? I cannot find the manufacturer for these and no one at any national
lab has either.  I would like to know what these are made of, without
trying to dismantle a working one.
