1. [AMPS] drive derived screen potential (score: 1): Author: nospam4me@juno.com (nospam4me@juno.com); Date: Sun, 19 Dec 1999 00:24:33 -0800; hello, I want to thank Ian and Colin for your quick replies about eh DAF circuit. Reminds me of a circuit used by Norm (w6edd) in his two 4cx250b amplifier. He controlled the screen voltage with driv; /archives//html/Amps/1999-12/msg00227.html (8,251 bytes)
2. [AMPS] drive derived screen potential (score: 1): Author: k7fm@teleport.com (Lamb); Date: Sun, 19 Dec 1999 08:46:14 -0800; Hi Skipp: There are perhaps 2 other reasons to use a circuit which derives screen voltage from the drive. The first is that it reduces dissipation in proportion to the speech, so that it is zero whil; /archives//html/Amps/1999-12/msg00234.html (10,349 bytes)
3. [AMPS] drive derived screen potential (score: 1): Author: measures@vcnet.com (measures); Date: Sun, 19 Dec 1999 09:46:13 -0700; Norm's DAF amplifier was one of the two amplifiers I measured. He eventually converted the amplifier to conventional Class AB1. A conventional screen supply for the 4cx250Bs is hardly large. Since s; /archives//html/Amps/1999-12/msg00236.html (9,641 bytes)
