1. [Amps] re resonating hv choke in hv power supply (score: 1): Author: "Fern Rivard" <crc@cyberlink.bc.ca>; Date: Sun, 30 Sep 2007 12:44:14 -0600; Thanks to all those who steered me in the right direction to resonate the choke in my hv ps for hb 8877 hf amplifier. I used my HP 200CD signal generator and isolated it from the choke with a 30K res; /archives//html/Amps/2007-09/msg00516.html (7,335 bytes)
2. [Amps] re resonating hv choke in hv power supply (score: 1): Author: Peter Chadwick <g3rzp@g3rzp.wanadoo.co.uk>; Date: Sun, 30 Sep 2007 22:39:06 +0200 (CEST); Fern, Do check how the choke inductance varies with DC through it. You may find you need a slightly bigger cap. If you get stuck, I may still have some fairly big 0.1mFd 5kV caps. Shipping to the US; /archives//html/Amps/2007-09/msg00520.html (6,928 bytes)

Setting the resonance slightly to the high side at low current is correct so; /archives//html/Amps/2007-09/msg00523.html (9,462 bytes)
