1. [AMPS] PushPull (score: 1): Author: firson@Radiolink.net (Firson, YD1BIH); Date: Tue, 25 Jul 2000 14:13:51 JAVT; Some friend told me that runing tube on pushpull will be give bigger power than parallel (for two tube). I don't really understand, could anybody here give some explanation. de Firson - YD1BIH ______; /archives//html/Amps/2000-07/msg00148.html (7,087 bytes)
2. [AMPS] PushPull (score: 1): Author: W8JI@contesting.com (Tom Rauch); Date: Tue, 25 Jul 2000 06:53:02 -0400; For RF amplifiers, if you are operating the tube close to the upper frequency limit, push pull can help stabilize the PA. It also reduces even harmonics. For power output, as a general rule, there i; /archives//html/Amps/2000-07/msg00150.html (7,341 bytes)
3. [AMPS] PushPull (score: 1): Author: N4NT@chartertn.net (Michael O. Hyder); Date: Tue, 25 Jul 2000 08:53:59 -0400; It may be that his friend was talking about audio amplifiers where tubes in push-pull can be run class B, giving greater efficiency than the single-ended parallel design which must be run class A or; /archives//html/Amps/2000-07/msg00151.html (8,100 bytes)
4. [AMPS] PushPull (score: 1): Author: 2@vc.net (measures); Date: Tue, 25 Jul 2000 06:13:02 -0700; This theory is yet another old wives' tale on ham radio. The engine for linear service is peak cathode emission. With two tubes in parallel, you get twice as much peak emission, but the tubes are cu; /archives//html/Amps/2000-07/msg00152.html (7,264 bytes)
5. [AMPS] PushPull (score: 1): Author: Peter_Chadwick@mitel.com (Peter Chadwick); Date: Tue, 25 Jul 2000 14:24:24 +0100; Push pull has some advantages at the higher frequencies, in that the tube capacities are effectively in series rather than in parallel. At RF, the theoretical power capabilities are the same; in prac; /archives//html/Amps/2000-07/msg00153.html (7,257 bytes)

[AMPS] PushPull (score: 1): Author: i4jmy@iol.it (i4jmy@iol.it); Date: Tue, 25 Jul 2000 17:08:29 +0200; Althougt uncommon on tubes because of the high impedances and the typical tuned outputs, a class B push pull broadband amplifier has advantages in a lower harmonic content and with the more simple an; /archives//html/Amps/2000-07/msg00154.html (8,281 bytes)
