1. [Amps] Safety choke question (score: 1): Author: Jim Barber <audioguy@q.com>; Date: Mon, 9 Jan 2012 02:20:34 -0800; So what do you all think about using an RF Parts RFC-3 (225 uh 1.5A 4KV) plate choke as the safety choke for a large HF amp? The supply is 4KV at up to 2A, bridge rectifier with 32uf of filter. Altho; /archives//html/Amps/2012-01/msg00114.html (7,451 bytes)

Re: [Amps] Safety choke question (score: 1): Author: "Carel, pc5m" <pc5m@xs4all.nl>; Date: Tue, 10 Jan 2012 19:13:20 +0100; Hi Jim, I suppose you would like to put that choke across the (50Ohm) output terminal ? Think 225uH is not needed at all to have negligible effect at 160mtrs. I would go for a reasonable sized toroid; /archives//html/Amps/2012-01/msg00117.html (8,857 bytes)

I don't think I can get enough inductance with any reasonably sized stack of powdered-iron cores, but perhaps ferrite. I'll check into it. Thanks, Jim N7CXI ________________________________; /archives//html/Amps/2012-01/msg00123.html (9,730 bytes)

Just dont use some slow clunky breaker. Carl KM1H ______________________________________; /archives//html/Amps/2012-01/msg00134.html (11,208 bytes)
