Re: [Amps] CW and High Voltage (score: 1): Author: "Phil Clements" <philc@texascellnet.com>; Date: Sun, 4 Sep 2005 16:15:44 -0500; I didn't, Rich, until 200-400 watt transceivers started hitting the market. My 3CX3000A7 and your 8171 would not be affected, but 400 watts into some of the popular smaller tubes might not be pruden; /archives//html/Amps/2005-09/msg00046.html (9,815 bytes)

Re: [Amps] CW and High Voltage (score: 1): Author: R.Measures <r@somis.org>; Date: Sun, 4 Sep 2005 14:56:42 -0700; An 8171 would show grid-I at 400w drive, but damage to the grid would be unlikely. According to Eimac, a 3cx3000A7 would be slightly under-driven at 400w. Richard L. Measures, AG6K, 805.386.3734. www; /archives//html/Amps/2005-09/msg00050.html (10,201 bytes)

Re: [Amps] CW and High Voltage (score: 1): Author: "Gary Schafer" <garyschafer@comcast.net>; Date: Mon, 5 Sep 2005 00:20:57 -0500; Best efficiency is obtained when the plate tune and load caps are tuned for maximum output with a given amount of drive. Tuning up at maximum power with full drive as is normally done gives best effi; /archives//html/Amps/2005-09/msg00051.html (12,525 bytes)

However, I am having difficulty with the term "full drive". Is it defined as the full output of the exciter or the maximum input rating; /archives//html/Amps/2005-09/msg00052.html (8,908 bytes)
26. Re: [Amps] CW and High Voltage (score: 1): Author: R.Measures <r@somis.org>; Date: Mon, 5 Sep 2005 09:36:35 -0700; I define "full drive" as what is required to bring the cathode-I up to the point where linearity is on the verge of decreasing. For a young 3-500Z, this is c. 420mA. If the anode-V is c. 3000, this r; /archives//html/Amps/2005-09/msg00056.html (9,870 bytes)

For a start, the subjects says "CW" for which you don't need a linear amplifier anyway. But consider the amplifier is for SSB use, for which it should be line; /archives//html/Amps/2005-09/msg00065.html (10,030 bytes)
