1. [Amps] plate bypass caps (score: 1): Author: "Steve Flood" <kk7uv@bresnan.net>; Date: Sun, 11 Jan 2009 18:38:04 -0700; I have an Ameritron plate choke mounted in my amp project. It is 225uH. With 2700 plate volts, this is 2544 ohms at 1.8 MHz and thus 1.06 amps. I am now assuming the plate bypass capacitor at the bas; /archives//html/Amps/2009-01/msg00093.html (7,555 bytes)

They are 5000 PF but just put two of them in parallel for .01 at 4KV. Steve said 2700 volts. So these should work fine?

Yes, they will be fine at the base of the plate choke; I use similar caps in my projects but use good doorknobs for blocking caps. Thanks.

Just please remember: the RF current at the choke's base can be quite high, so RF withstanding current must be quite high!
