1. [Amps] Tuned input for 2 x GS 31 B (score: 1): Author: "Geert Hofman" <Geert_Hofman@Jabil.com>; Date: Tue, 3 Jan 2006 18:12:23 -0000; I am working on a contest amplifier with 2 x GS 31B which should run smoothly (cool) at 1.5 kW RTTY. Prepared the tuned input circuit based on a Q of 2 for all contest bands ( so 50 to 25 Ohms impeda; /archives//html/Amps/2006-01/msg00146.html (8,800 bytes)

Re: [Amps] Tuned input for 2 x GS 31 B (score: 1): Author: "Phil Clements" <philc@texascellnet.com>; Date: Tue, 3 Jan 2006 12:25:49 -0600; The tuned input must be adjusted at full output out of the amp. Perhaps someone can furnish you their final values obtained from a working similar amp. This will save you a lot of trial and error ti; /archives//html/Amps/2006-01/msg00149.html (8,055 bytes)

5. Re: [Amps] Tuned input for 2 x GS 31 B (score: 1): Author: TexasRF@aol.com; Date: Wed, 4 Jan 2006 10:32:59 EST; If this was already covered please excuse my redundancy. The input capacitance of the GS31B is likely on the order of 22pf. Two of them 44pf. These values as well as any strays in the circuit have to; /archives//html/Amps/2006-01/msg00163.html (10,082 bytes)
