Capacitors
The ECW series caps are metallized polypropylene (self-healing) and are designed for applications where high frequency & high pulse are required. I've been using these in mmc's for 7 years with great results.
Panasonic ECW-H15H432F7, 2500Vdc, 0.0043uf, 3% tol., factory sealed bags of 100, $50.00, production of this voltage (2500Vdc) discontinued due to lack of sales. I have also critically measured and sorted by exact value several hundred of these caps - call me regarding these.

Here's an MMC using 104 of these caps
Mars Pathfinder Caps - 5kV 4700pF, 10 pieces, each has its own plastic box with both having matching serial numbers, the second Pathfinder photo below is a head-on shot of a cap where the serial number is stamped. 4/5" square. The rest of these are sitting on Mars. Could be a cool component for a project. Make Offer.
Pathfinder Observer
Mars Observer Caps - 10kV 560pF, 10 pieces. The others were ground to pieces in an unfortunate collision with Mars due to a measurement conversion error. Each cap and its box have matching serial numbers. Make Offer.
Current
Limiting: D&M's High Voltage, We offer variable reactors (slide
chokes) in a commercial version for this application (current limiting or
ballasting tesla coils). You can see a

Adjustable topload support - click on that link and look at photos 6, 7 & 8 and read the commentary. That should allow you to build one. If you have any questions, email me, I'll be glad to assist. I have built these for others but need a 5" section of the form in question as this support requires precise fitting.
Antique Flux meter - WY0023 Flux meter No. 1, complete, original and in beautiful condition. Stamped 'Made In England'. Used for measuring the magnetic flux of magnets. I've been searching for another one for over 4 years without result. The Royal Electrical and Mechanical Engineers Museum has some reference material on one used by the British Army but no meter. I can't even find a museum or collector that has one of these. Manufacture date unknown but I think it dates from the 1930's to early 1940's. This is a very rare meter and it would be nice for it end up in a museum or collection. Click on a photo number. 1 2 3 4 5 6 7 8 9 Make an offer.
Bi-Polar Tesla Coil - This is the coil on the Bi-Polar TC page. I'm building a new one and need the space in my front room for it. $5,000.00, includes delivery in California, all associated equipment and a new acrylic plasma chamber. Lots of video available.
Lichtenberg Figures - Stoneridge Engineering now offers 19 sizes and styles of Lichtenberg Figures ranging from affordable 2" x 2" through huge 12" x 12" x 1" museum quality specimens. Unfortunately, a commercial source for Lichtenberg Figures, Acsion, in Canada, no longer produces them. http://205.243.100.155/frames/interesting.html
“A physical experiment which makes a bang is always worth more than a quiet one. Therefore a man cannot strongly enough ask of Heaven: If it wants to let him discover something, may it be something that makes a bang. It will resound into eternity.” Georg Christoph Lichtenberg 1742-1799.
