1. [Amps] D.C. on filaments of GS-35B? (score: 1): Author: nemo zilch <nemozilch@gmail.com>; Date: Fri, 30 Jan 2015 17:31:50 -0500; Seems to me it would be good to use a dc supply for the filament of the GS35B amp I am building. Easier to build an effective soft start circuit, easy to build the supply. I understand why dc is not; /archives//html/Amps/2015-01/msg00380.html (6,837 bytes)

I would like to know the pros and cons of running the filaments of an GS-35 with Vdc , you can get small power supply of 15, 24 or 30Vdc at 10A, by around $30 some with 3 way out, you can; /archives//html/Amps/2015-02/msg00042.html (7,859 bytes)
