1. [AMPS] screen voltage supply (score: 1): Author: km3g@cts.com (Lane C. Zeitler); Date: Thu, 17 Jul 1997 23:54:10 -0700; Has anyone tried tapping off of the B+ via a dropping resistor to provide screen voltage to a tetrode? If you only need a 100ma or less wouldn't this work? With acceptable E regulation? Any comments; /archives//html/Amps/1997-07/msg00116.html (7,267 bytes)
2. [AMPS] screen voltage supply (score: 1): Author: km1h@juno.com (km1h @ juno.com); Date: Fri, 18 Jul 1997 08:25:09 EDT; That is the acceptable way of doing it Lane since then if the HV fails the screen supply goes away also. Using a seperate screen supply without full protection circuitry is asking for trouble. The 4-; /archives//html/Amps/1997-07/msg00118.html (8,299 bytes)
3. [AMPS] screen voltage supply (score: 1): Author: measures@vc.net (Rich Measures); Date: Fri, 18 Jul 97 06:10:02 -0700; Sure. A dropping R and a zener string shunt screen-regulator is preferred for smallish AB1 amplifiers with minimal screen current requirements. regulation? Yes. However, if the anode supply was 9kV; /archives//html/Amps/1997-07/msg00120.html (7,761 bytes)
4. [AMPS] screen voltage supply (score: 1): Author: n6tr@teleport.com (Larry Tyree); Date: Fri, 18 Jul 1997 06:26:22 -0700 (PDT); Hi Lane I have seen this technique discussed and used for some low power transmitters. 100 ma is a lot to do this with (depending on the voltage drop you need). For example, 2KV at 100 ma is quite a; /archives//html/Amps/1997-07/msg00122.html (8,005 bytes)
5. [AMPS] screen voltage supply (score: 1): Author: lanej@provide.net (John Lane); Date: Fri, 18 Jul 1997 11:29:50 -0400; This is commonly done. An example is the screen supply in the AM-6155 amplifier. It has the advantage that the screen supply drops with the anode supply in a fault condition. A disadvantage is the po; /archives//html/Amps/1997-07/msg00129.html (7,604 bytes)
6. [AMPS] screen voltage supply (score: 1): Author: G3SEK@ifwtech.demon.co.uk (Ian White, G3SEK); Date: Fri, 18 Jul 1997 12:50:55 +0100; Yes, it's a common technique - it can be very power-hungry (work out the wattage of the dropper resistor) but it does have the advantage that screen voltage is automatically removed if the B+ fails.; /archives//html/Amps/1997-07/msg00136.html (8,456 bytes)
