Is there a handy rule of thumb as to how much to derate an energy-storage capacitor when one wishes to use it in dc filter service? I understand that the energy-storage types (flashdischarge) are des

This is of great interest, Rich. Let us suppose that the plates are ultra thin, but that the insulation is of the standard dimension. If that be true, *voltage* ceases to be the issue. Instead, *curr

Hey, Rich, why stop there? Didn't Continental Electronics employ *water* cooling of the tank coil in some of their big boys? :-) 73 de Bob, K0KR -- FAQ on WWW: http://www.contesting.com/ampfaq.html S

Lest anyone worry that the parasitic oscillation thread is losing steam (or is that smoke?), I thought some might find interesting a comment I received from a buddy of mine off line: 73 de Bob, K0KR

The Henry 2K has been around in one version or another for approximately 30 years. Henry produced so many variations on the design over the years that it is difficult from memory alone to be confiden

Agreed. My copy of Bill Orr's Radio Handbook shows one version of a grid over-current protection circuit designed, as I recall, by W8ZR. Some years ago, a fellow (might have been ZR) was selling prin
