1. [AMPS] Plate Load impedance (score: 1): Author: irosky@yahoo.com (igor rosky); Date: Sat, 26 Sep 1998 20:21:30 -0700 (PDT); I never get my plate load impedence calculation to agree with Eimac data sheets, how does eimac calculate plate load impedance? For ab1 amplifiers is the multiplying factor 1.8 or 2? Or what is the c; /archives//html/Amps/1998-09/msg00282.html (7,134 bytes)
2. [AMPS] Plate Load impedance (score: 1): Author: measures@vc.net (Rich Measures); Date: Sun, 27 Sep 98 01:38:33 -0800; Depends on the zsac. Either figure is close enough. I use [E-anode/2x I-anode] for tetrodes with handles. - later, Igor Rich... R. L.

Hallam" <dhallam@rapidsys.com>; Date: Mon, 6 Sep 2004 21:26:06 -0400; I am going through the exercise to design the Pi-L network for a new amplifier. Calculating the plate load impedance by two different methods, I come up with two vastly different answers. With a tetr; /archives//html/Amps/2004-09/msg00145.html (7,371 bytes)

5. [Amps] Plate Load Impedance (score: 1): Author: Will Matney <craxd1@ezwv.com>; Date: Tue, 07 Sep 2004 07:33:50 -0400; David, Generally, knowing what the output will be in watts and the duty cycle will determine the plate current. Then it's should be the plate resistance = plate voltage / plate current. Try using the; /archives//html/Amps/2004-09/msg00154.html (8,182 bytes)
6. Re: [Amps] Plate Load Impedance (score: 1): Author: TexasRF@aol.com; Date: Tue, 7 Sep 2004 10:28:39 EDT; The RCA Power Tube book shows plate load impedance= (plt voltage/plt current)/K factor. Note that plate voltage is the d.c. value from the power supply and plate current is as measured by the d.c. pl; /archives//html/Amps/2004-09/msg00160.html (7,889 bytes)
7. RE: [Amps] Plate Load Impedance (score: 1): Author: "David C. Hallam" <dhallam@rapidsys.com>; Date: Thu, 9 Sep 2004 16:38:28 -0400; Gerald, I pulled out my copy of the RCA tube manual and read the section on AB1 amplifiers. I didn?t find anything that explicitly referred to a K factor for AB1, but then maybe my edition is an olde; /archives//html/Amps/2004-09/msg00175.html (9,512 bytes)
8. Re: [Amps] Plate Load Impedance (score: 1): Author: Will Matney <craxd1@ezwv.com>; Date: Fri, 10 Sep 2004 09:22:45 -0400; Gerald, I just noticed the below formula and it didn't look quite right. Probably a misprint. Anyhow, plate resistance; RP = EP / 1.8 X IP 1.8 = K factor for class AB1 (Changes with ZSAC) RP = Plate; /archives//html/Amps/2004-09/msg00185.html (9,127 bytes)
