1. [Amps] Glow, gettering, and voltage (score: 1): Author: Catherine James <catherine.james@att.net>; Date: Sat, 7 Jan 2017 09:01:08 -0800; I've noticed an interesting effect with the 3-500Z tubes in my SB-220. When I run a kilowatt SSB on the low voltage setting on low HF bands, there is very little glow. When I run the same power on th; /archives//html/Amps/2017-01/msg00152.html (7,308 bytes)

Re: [Amps] Glow, gettering, and voltage (score: 1): Author: <w8hw@comcast.net>; Date: Sat, 7 Jan 2017 12:36:15 -0500; Hello Cathy, The answer is increased "RESTING" plate current in high voltage position. Resting plate current does NOT produce any RF, so it becomes 100% heat and 0% RF. The plates dissipate extra pow; /archives//html/Amps/2017-01/msg00153.html (8,080 bytes)

It had not occurred to me that it is simply due to higher bias current at the higher plate voltage. 73, Cathy _______________________________________________ Amps mailing list Amps@conte; /archives//html/Amps/2017-01/msg00159.html (6,934 bytes)

Re: [Amps] Glow, gettering, and voltage (score: 1): Author: Manfred Mornhinweg <manfred@ludens.cl>; Date: Sun, 08 Jan 2017 14:51:18 +0000; Hi Cathy, Jim, and all, I agree that a part of the higher dissipation is caused by higher idle current, multiplied by higher plate voltage. But I think that you are wrong in a few points here, Jim, a; /archives//html/Amps/2017-01/msg00176.html (9,697 bytes)

Re: [Amps] Glow, gettering, and voltage (score: 1): Author: Catherine James <catherine.james@att.net>; Date: Sun, 8 Jan 2017 08:46:28 -0800; I tuned for peak power at the higher voltage, advanced the load control a bit more, and operated there.

Re: [Amps] Glow, gettering, and voltage (score: 1): Author: Joe <nss@mwt.net>; Date: Sun, 8 Jan 2017 10:54:17 -0600; Put in the controlled bias circuit and they won't glow unless youre running RTTY or similar. And you can leave it in the SSB position all the time. Joe WB9SBD Sig The Original Rolling Ball Clock Idle; /archives//html/Amps/2017-01/msg00184.html (8,359 bytes)

Re: [Amps] Glow, gettering, and voltage (score: 1): Author: Dick NY1E <dick@ny1e.com>; Date: Mon, 9 Jan 2017 14:11:56 +0000 (UTC); I do not want to wear out the unobtainium CW/SSB switch by going back and forth every time I use the amp. I want to pick one voltage setting and do 95% of my operation there. 73, Cathy N5WVR I do jus; /archives//html/Amps/2017-01/msg00195.html (8,294 bytes)

Re: [Amps] Glow, gettering, and voltage (score: 1): Author: Joe <nss@mwt.net>; Date: Mon, 9 Jan 2017 08:23:06 -0600; Thing is, If you were to stick with just one voltage, and say the switch did go bad, what is wrong with just by-passing the switch all together and just connect the wires to each other as the switch; /archives//html/Amps/2017-01/msg00196.html (8,806 bytes)

Re: [Amps] Glow, gettering, and voltage (score: 1): Author: Roger D Johnson <n1rj@roadrunner.com>; Date: Mon, 09 Jan 2017 12:19:14 -0500; Switching between CW and SSB voltages doesn't stress the switch much. Turning the amp on results in a large surge through the on/off switch. This can be minimized by starting the amp in the CW positi; /archives//html/Amps/2017-01/msg00198.html (9,799 bytes)
