[Amps] (no subject)

[Dan Hearn]

I should have given the physical size of the caps. They are 4 x 4 1/2 x 9 inches. They are much larger than the de-fib caps shown on the Aerovox page. I think they came from some university lab surplus. Pulse Laser maybe? I will probably have some of them at Puyallup hamfest.

Hi Dan:

They are defib caps.  At least one manufacturer said they should not be used at more than 2/3 of the rated voltage for continuous use.  Hams regularly use them with those ratings.  I use a pair decades ago in a voltage doubling circuit.  The voltage was 4 KV, divided among the two caps.  The amp is still running flawlessly.
