1. [Amps] Question about separate power supply/RF section amp (score: 1): Author: Vic K2VCO <k2vco.vic@gmail.com>; Date: Thu, 17 Jan 2013 13:00:07 -0800; I'm building an amplifier with a separate power supply. The PS is a unit that sits on the floor. I wanted a small desktop amp and there's no room for a rack. In the power supply section, I have a 0.3; /archives//html/Amps/2013-01/msg00100.html (8,049 bytes)

Normally you only need one diode for protection from; /archives//html/Amps/2013-01/msg00101.html (7,978 bytes)

Re: [Amps] Question about separate power supply/RF section amp (score: 1): Author: TexasRF@aol.com; Date: Thu, 17 Jan 2013 20:59:33 -0500 (EST); Hi Vic, as you say, installing another diode inside the amplifier can't hurt so why not? The only downside that comes to mind is that the added diode could be the one that fails due to an arc and mig; /archives//html/Amps/2013-01/msg00103.html (9,218 bytes)

A type 6A10 has a surge rating of 400 amps. Should be enough.

I am thinking of adding another diode from B- to chassis in the RF section. I don't see how this could hurt, but it might help clamp the voltage in; /archives//html/Amps/2013-01/msg00108.html (9,066 bytes)

I think I will use an additional diode, or two as W6WRT suggested. Yes, I always use a 20-ohm glitch resistor, which I put in the amplifier. The power supply has a pair of 15A breakers.
