The rate is 20x the current subscription rate - has been for at least 30 years. I paid $135 (20 x $6.75) in 1975-ish just before the rate went to $8.25/year or $165/life. Mike N2MG

Fixed Vacuum Caps
So I went ahead and put some whiskers, er, feelers out for info on fixed vacuum capacitors in high voltage service. Info Item 1: Glass fixed vacuum capacitors are used in DC + RF applications as

Re: AC HiPot tester question
I have done this, Mike, but one must be careful not to overdo the procedure. To begin with, connect a 20M to 100M HV-rated resistor in series with the high-potential tester to seriously limit current.

Re: Fried glitch R...... from an oversized HV fuse
The critical thing is: at what potential does the unit begin to conduct current.

At the potential required to effect a change the resulting amperage might be deleterious. Why not e-mail Jennings to see their fix? Hal W4HBM

Re: AC HiPot tester question
Now, let me ask a question of social and political importance: Is it possible to 'remove' the whisker by introducing and hi(er)-voltage to the vacuum cap? The reason I ask is that this was practice

Re: Rich tells us how to Ram 300+ A through a 40 A breaker.
Correct My guess is that the efficiency was closer to 60%. Only if one assumes that the filter-C stores zero Joules in the 70% interim between 30pps, 30% duty-cycle tuning pulses. . The mains ESR was
