Preparing for an SK sale, I found a 2000pF vacuum capacitor rated at 8kV which has a small star crack going through the glass, so it isn't a vacuum cap any more. However, on the hi-pot tester it is s

Worst case is that the crack will continue due to thermocycling or you could have a partial vacuum, apparently already up to atmosphere, which could reduce the break down voltage to a few hundred vol

REPLY: There is apparently already an air leak. This kind of damage only gets worse with time. I'd junk it. Bill, W6WRT _______________________________________________ Amps mailing list Amps@contesti

worse Sorry, I should have made that clearer. The damage happened a long time ago, so it is already up to 100% of atmospheric pressure. It will still hold off 3kV DC. 73 from Ian GM3SEK ____________

27/04/2013 21:03 Quite why they don't have a means of checking or re-evacuating these things I don't know. Some sort of port would be nice, given the price, even if you needed fairly specialised gea

Hello all, My wife has a woman working for her at her art gallery that is also an experienced 'glass artisan', or whatever the name is, and I asked her about working with the glass vac variables. She

I have had a lot of experience with working with glass blowers and stuff like that. It seems that if you try to repair a crack in glass as soon as you start heating the object up the crack grows due
