- Hi My military sources tell me that they can get anything they can imagine...but not necessarily at a price you'd want to pay. Plain ol' silicone spark plug wire is fine for HV to a few amps, and you

- No, not really stupid questions. Just two questions I haven't asked before. Let's say I had a whole bunch of 0.1 uF disk capacitors, all the same size and all rated at 5 kV. Is there any reason I cou

- These wonderful parts are variations on a theme -- APT has quietly been building these things for years, though at lesser power and frequency specs. They have some interesting app notes on their webs

- OK, only stupid because I never asked it. Yet. What determines the capacitance value for a plate-blocking capacitor? By this I mean the capacitor (usually a doorknob cap) between the plate choke and

- So in theory, if I had a capacitor that could pass the current and withstand the DC, almost any value low enough not to "tweak" the palte impedance would work. This might be a way to use up all those

- Check the math -- 1% is 20 watts on a 2 KW amp -- a real doorknob cap would be fine. However, as Mr. Measures pointed out, current at 30 MHz can be considerable, and I^2R effects will push losses up.
