Re: [Amps] An inexpensive choke for a resonant filter (score: 1): Author: Angel Vilaseca <avilaseca@bluewin.ch>; Date: Wed, 16 May 2007 07:45:24 +0200; Jim I see from your simulation that a 2 H inductance is typical for a HV secondary. I wonder if a HV transformer from a microwave oven cold be recycled in a HV power supply, using its secondary windi; /archives//html/Amps/2007-05/msg00140.html (11,128 bytes)

Re: [Amps] An inexpensive choke for a resonant filter (score: 1): Author: Vic K2VCO <vic@rakefet.com>; Date: Wed, 16 May 2007 08:10:27 -0700; I have one of these and it looks like one side of the secondary is designed to be grounded. So the insulation may be poor at this point. If this is the case with yours, you might think about using it; /archives//html/Amps/2007-05/msg00141.html (8,217 bytes)

Re: [Amps] An inexpensive choke for a resonant filter (score: 1): Author: Steve Thompson <g8gsq@eltac.co.uk>; Date: Wed, 16 May 2007 17:31:40 +0100; I have three here I'm experimenting with (as HV supplies). I lifted the grounded end of the secondary on all of them - two hipot to 8kV+, the third arcs at 3kV but a piece of Kapton tape on the frame; /archives//html/Amps/2007-05/msg00142.html (8,846 bytes)

Re: [Amps] An inexpensive choke for a resonant filter (score: 1): Author: Angel Vilaseca <AVILASECA@BLUEWIN.CH>; Date: Thu, 17 May 2007 10:13:43 +0200; Marv, Thank you for this very useful information. Maybe the primary of a microwave oven could be wired in series with the secondary (forward or backwards, depending on the inductance you want) and be; /archives//html/Amps/2007-05/msg00145.html (10,404 bytes)
