1. [Amps] stepper motors (score: 1): Author: KD7QAE <KD7QAE@ARRL.NET>; Date: Thu, 15 Sep 2005 02:44:12 +0100; I am (still) in the process of designing my dual gs35b amp and would like some advice on stepper motor selection. I have 2 Russian vacuum variable caps that I want to motorize and wonder if anyone on; /archives//html/Amps/2005-09/msg00124.html (6,986 bytes)
