1. [Amps] Hi Mu correction (score: 1): Author: "Tom W8JI" <w8ji@w8ji.com>; Date: Tue, 18 Jul 2006 22:55:55 -0400; I do think I made an error in the post about mu, but I deleted my post. Higher mu in a given tube means less bias is needed to maintain the same plate current. Lower mu means more bias is needed to c; /archives//html/Amps/2006-07/msg00612.html (6,296 bytes)

I thought that a higher mu tube (higher gain) would require more bias to hold it to a specific current (idle?) and that a lower mu tube (lower gain) would require le; /archives//html/Amps/2006-07/msg00613.html (6,883 bytes)

Lower mu tubes need more bias to maintain a certain plate current, all other things equal.This means lower mu tubes of a given type have more idle current at a certain b; /archives//html/Amps/2006-07/msg00614.html (7,907 bytes)

Re: [Amps] Hi Mu correction (score: 1): Author: Bill Fuqua <wlfuqu00@uky.edu>; Date: Wed, 19 Jul 2006 10:49:21 -0400; Lower mu tubes have wider spacing between the grid wires allowing more electrons to slip by each second for the same bias voltage. It also reduces the effective control the grid voltage has over the; /archives//html/Amps/2006-07/msg00634.html (8,615 bytes)

Re: [Amps] Hi Mu correction (score: 1): Author: Mark Hill <g4fph@mjha.co.uk>; Date: Wed, 19 Jul 2006 17:06:17 +0100; Folks, Just after I was first licensed, I built an HF amp. with a pair of zero-cost, QY4-400 (tetrode strapped as triode). I put a few Volt of positive DC on the cathode to get the ZSAC to what I tho; /archives//html/Amps/2006-07/msg00638.html (10,886 bytes)
