1. [AMPS] B+resistors (score: 1): Author: Peter.Chadwick@gpsemi.com (Peter Chadwick); Date: Thu, 9 Oct 1997 17:18:13 +0100; Rich, Have you any comments about using big solid carbon or metal film resistors - things like 50ohm, 50 watt metal film tubular resistors NOT spirally cut, as are/were made for dummy loads? Similarl; /archives//html/Amps/1997-10/msg00053.html (7,917 bytes)
2. [AMPS] B+resistors (score: 1): Author: measures@vc.net (Rich Measures); Date: Thu, 9 Oct 97 10:24:41 -0800; Spiral-cutting would reduce the voltage-gradient in the resistive material. My opinion is try it. If the resistor does not fail during a test, it's probably going to do the job of limiting peak faul; /archives//html/Amps/1997-10/msg00054.html (9,229 bytes)
3. [AMPS] B+resistors (score: 1): Author: km1h@juno.com (km1h @ juno.com); Date: Thu, 09 Oct 1997 16:01:59 EDT; Rich, Peter, et al: I prefer the standard "Brown Devil" style of resistor. Here is why. The resistance wire is made from that N Word stuff. Along with the current limiting which is the primary purpos; /archives//html/Amps/1997-10/msg00055.html (11,077 bytes)
4. [AMPS] B+resistors (score: 1): Author: measures@vc.net (Rich Measures); Date: Fri, 10 Oct 97 00:22:28 -0800; agreed problems IF a 1000pF capacitor bypasses RF from the anode circuit, it seems unlikely that much VHF energy could get past that bypass and invade the glitch resistor. However, 6.3 ohms is likel; /archives//html/Amps/1997-10/msg00057.html (11,609 bytes)
5. [AMPS] B+resistors (score: 1): Author: km1h@juno.com (km1h @ juno.com); Date: Fri, 10 Oct 1997 09:54:51 EDT; SNIPS In the SB-220 that 1000pf bypass cap is highly reactive at VHF. It is not RF rated. However replacing with a 1000pf disc ceramic with very short leads will do the job. As I tried to allude to e; /archives//html/Amps/1997-10/msg00060.html (11,369 bytes)
6. [AMPS] B+resistors (score: 1): Author: measures@vc.net (Rich Measures); Date: Fri, 10 Oct 97 11:35:15 -0800; ... ... What is the resonant frequency of this capacitor with a wide copper-foil short across it? I do not see how. The vhf choke, RFC-2, (or it's replacement, the glitch R) is some distance from th; /archives//html/Amps/1997-10/msg00062.html (8,250 bytes)
7. [AMPS] B+resistors (score: 1): Author: km1h@juno.com (km1h @ juno.com); Date: Fri, 10 Oct 1997 17:56:06 EDT; I'll measure some time and let you know. I never said the chokes were damaged but we have all seen damage to the zener which sticks right into the RF field plus other PS damage. Parasitics IMO were n; /archives//html/Amps/1997-10/msg00063.html (8,263 bytes)
