1. [Amps] Help constructing filament choke for pair of 3-500Zs on 6 m (score: 1): Author: John Farber <kg6i@comcast.net>; Date: Fri, 28 Jun 2013 16:02:58 +0000 (UTC); I could use some info on constructing a suitable filament choke for a pair of 3-500Zs on 6 m, my current amp project. My gut feeling is a standard choke design for 80-10 would not be correct due to t; /archives//html/Amps/2013-06/msg00266.html (7,091 bytes)

A reactance of 10 times the input impedance of the tubes is sufficient to have the choke "invisible" to the input RF.

I've moded quite a few amps for 6 M and I remove half the turns from the original choke. This reduces the inductance by a factor 4 and wor; /archives//html/Amps/2013-06/msg00268.html (9,292 bytes)
