1. [AMPS] G2DAF amps (score: 1): Author: Peter.Chadwick@gpsemi.com (Peter Chadwick); Date: Mon, 15 Dec 1997 12:18:53 -0000; There was a lot of discussion in the pages of the then RSGB Bulletin when G2DAF first described the circuit. G6JP was extremely dubious about it. I guess that it is possible to analyse it: it will de; /archives//html/Amps/1997-12/msg00296.html (8,131 bytes)
2. [AMPS] G2DAF amps (score: 1): Author: measures@vc.net (Rich Measures); Date: Mon, 15 Dec 97 06:32:03 -0800; ... ... ... The G2DAF circuit's screen voltage remains constant during such tests. However, with voice modulation, the screen voltage - and the IMD - fluctuate wildly. One of the more curious things; /archives//html/Amps/1997-12/msg00297.html (7,524 bytes)
3. [AMPS] G2DAF amps (score: 1): Author: lars.harlin@pocab.se (Lars Harlin); Date: Mon, 15 Dec 1997 17:08:55 +0100; Peter Chadwick: Rich Measures: * This is not true. The screen voltage will most certainly fluctuate, as thats * the general idea with the circuit. However, that does not mean that IMD also * "fluctua; /archives//html/Amps/1997-12/msg00300.html (8,737 bytes)
4. [AMPS] G2DAF amps (score: 1): Author: measures@vc.net (Rich Measures); Date: Mon, 15 Dec 97 08:59:42 -0800; Eimac says that fluctuating screen voltage increases distortion. I'd say that a total IMD of roughly -22db below PEP seems pretty wild to this non-expert. . - Perhaps the reason that screen voltage; /archives//html/Amps/1997-12/msg00301.html (8,049 bytes)
5. [AMPS] G2DAF amps (score: 1): Author: G3SEK@ifwtech.demon.co.uk (Ian White, G3SEK); Date: Mon, 15 Dec 1997 13:12:03 +0000; To simulate the whole spectral content of speech, you'd have to go all the way down to about 1Hz (the word or syllable rate) for the third 'tone' because this is where many poorly-regulated anode and; /archives//html/Amps/1997-12/msg00302.html (8,276 bytes)
