1. [AMPS] G2DAF and super cathode (score: 1): Author: sm5ki@algonet.se (sm5ki); Date: Thu, 16 Dec 1999 21:59:07 +0000; Before talking down the G2DAF circuit I may ask has anybody measured the distorsion in it? Where and when was this published? There is much about the G2DAF in Pat Hawkers TECHNICAL TOPICS SCRAPBOOK 1; /archives//html/Amps/1999-12/msg00194.html (13,557 bytes)
2. [AMPS] G2DAF and super cathode (score: 1): Author: measures@vcnet.com (measures); Date: Thu, 16 Dec 1999 20:04:57 -0700; Yes. In two units the total IMD was c. -22db below peak envelope power. One DAF amplifier used 813s. The other used 4CX250Bs. It was published live on the 40m band whenever people were being interfe; /archives//html/Amps/1999-12/msg00200.html (10,506 bytes)

4. SV: [AMPS] G2DAF and super cathode (score: 1): Author: measures@vcnet.com (measures); Date: Fri, 17 Dec 1999 06:27:18 -0700; Quite the opposite. With a two-tone standard test, the DAF config. operates the screen at constant potential, the distortion looks ok, and there is no clue about what will occur during voice modulat; /archives//html/Amps/1999-12/msg00209.html (11,571 bytes)
5. [AMPS] G2DAF and super cathode (score: 1): Author: nospam4me@juno.com (nospam4me@juno.com); Date: Sat, 18 Dec 1999 11:57:10 -0800; OK, I missed the start of all this again. Is the G2DAF design just another super cathode drive amplifier? ... or is the hook for the circuit a positive potential on the screen grid..? Someone please; /archives//html/Amps/1999-12/msg00222.html (9,001 bytes)
6. [AMPS] G2DAF and super cathode (score: 1): Author: G3SEK@ifwtech.demon.co.uk (Ian White, G3SEK); Date: Sat, 18 Dec 1999 23:23:30 +0000; The G2DAF is grid driven across a load resistor, with grounded cathode. The unique feature is that it has neither grid bias nor permanent screen voltage. Instead, the screen voltage is derived by vol; /archives//html/Amps/1999-12/msg00224.html (9,702 bytes)
