1. [Amps] filament on 3cpx800 (score: 1): Author: George Cortez Jr <ne2i@optonline.net>; Date: Sun, 08 Feb 2009 18:20:31 -0500; I see the filament voltage is 13.5 volts at 1.5 amps. My alpha conversion uses a 12.6volts on the filaments. Can I gain efficiency and more power going closer to the required voltage? Am I hurting an; /archives//html/Amps/2009-02/msg00209.html (6,916 bytes)

Working on a similar issue here- the alternatives were using the 12.6VAC tap to build a DC supply (12.6 x 1.414) & then regulating it down to 13.5VDC.

If its below 12.9V RMS then get a higher amperage 12.6V transformer which wont be loaded down as much; you only need .3V more to be within the lo; /archives//html/Amps/2009-02/msg00214.html (8,031 bytes)
