1. [AMPS] Stability Question (score: 1): Author: jono@enteract.com (Jon Ogden); Date: Sat, 6 Feb 1999 19:39:19 -0600; Quiz time! I am finally at the point in putting my amp back together where I can run some stability tests. And I have come up with a question/problem. Here's how I am testing: Key up amp, no RF, Ctun; /archives//html/Amps/1999-02/msg00226.html (8,725 bytes)
2. [AMPS] Stability Question (score: 1): Author: royanjoy@ncn.net (Roy Koeppe); Date: Sun, 7 Feb 1999 08:56:01 -0600; Determine the oscillation freq.

Try it with real world tuning values and then remove the load. A good layout should then be stable. In a perfect world what you are; /archives//html/Amps/1999-02/msg00243.html (11,396 bytes)

5. [AMPS] Stability Question (score: 1): Author: jono@enteract.com (Jon Ogden); Date: Mon, 8 Feb 99 15:55:51 -0600; OK. Well, I guess I am just of the school that wants an amplifier to be bullet proof. Under "reasonable" real world values, I have no oscillation. It's just when my turns counter on my UCS-300 gets; /archives//html/Amps/1999-02/msg00250.html (12,228 bytes)
6. [AMPS] Stability Question (score: 1): Author: km1h@juno.com (km1h@juno.com); Date: Tue, 9 Feb 1999 10:54:22 -0500; Does that tube produce more power than the rest? Is it a different brand? You probably need 3 hands. Just barely start oscillating and tune the GDO; keep it as far away as necessary to get a half sca; /archives//html/Amps/1999-02/msg00272.html (15,362 bytes)
7. [AMPS] Stability Question (score: 1): Author: measures@vc.net (Rich Measures); Date: Tue, 9 Feb 1999 04:42:44 -0800; ? The setting of L and C-load are not substantive factors, nor is the HF load, because L is pretty much like a vhf choke. . The resonant circuit that supports a vhf parasite is formed by lead induct; /archives//html/Amps/1999-02/msg00275.html (9,120 bytes)
8. [AMPS] Stability Question (score: 1): Author: jono@enteract.com (Jon Ogden); Date: Tue, 9 Feb 1999 20:08:54 -0600; Both are Eimac. My only other "good" tube was destroyed by my oscillation last spring, it turns out. The filaments don't even light! I haven't really quantified which tube puts out more power since; /archives//html/Amps/1999-02/msg00284.html (9,764 bytes)

Dont worry about 80 for now, I've never had problems down there with the 850 as-is. Trimmers vary roughly; /archives//html/Amps/1999-02/msg00292.html (10,570 bytes)
