2. [AMPS] Tuning question (score: 1): Author: 2@vc.net (2); Date: Thu, 8 Nov 2001 11:35:42 -0800; so, why? Grid current varies from tube to tube, so grid current is pretty much moot in AB2 g-g service. Grid current and screen current is important in Class AB1 amplifiers. The grid bias V should b; /archives//html/Amps/2001-11/msg00148.html (9,753 bytes)
3. [AMPS] Tuning question (score: 1): Author: Peter.Chadwick@zarlink.com (Peter Chadwick); Date: Fri, 9 Nov 2001 07:35:59 -0000; Conventional amps should be tuned at 100%, as Rich says. However, this doesn't necessarily apply if the amp has circuitry that allows correct tuning and loading to be achieved at lower power levels.; /archives//html/Amps/2001-11/msg00153.html (8,797 bytes)
4. [AMPS] Tuning question (score: 1): Author: 2@vc.net (2); Date: Fri, 9 Nov 2001 05:48:02 -0800; // Tuning up an amplifier is basically about adjusting the tank to match RL to R-load - usually 50-ohms. The sticky wicket is that RL is a function of E/I. Maintaining this ratio is important in ach; /archives//html/Amps/2001-11/msg00154.html (10,297 bytes)
5. [AMPS] Tuning question (score: 1): Author: Peter.Chadwick@zarlink.com (Peter Chadwick); Date: Fri, 9 Nov 2001 13:47:53 -0000; I think that depends. Let's assume that your amp can produce the full wack single tone when tuned for 10 seconds or more - then if you're reasonably quick, you can do quite well without. However, yea; /archives//html/Amps/2001-11/msg00155.html (8,812 bytes)

An accurate tune for SSB requires that the tuneup and the operating potentials not be far apart. to // chortle cheers, Peter - R. L.

If the amp dissipates more power when running less output, crank 'er up.
