1. [Amps] Tube Class C operation no Drive power or grid current (score: 1): Author: "Fuqua, William L." <wlfuqu00@uky.edu>; Date: Sat, 8 Oct 2022 18:37:40 +0000; Maybe I have not looked at the data sheets very closely , but I was surprised to find a medium power glass Pentode that required zero grid current, thus no drive power in class-C operation.

(CW, FM, PM) Notice not the same for 2kV plate voltage but same efficiency. 73 Bill wa4lav ___; /archives//html/Amps/2022-10/msg00013.html (9,669 bytes)

Re: [Amps] Tube Class C operation no Drive power or grid current (score: 1): Author: sm0aom--- via Amps <amps@contesting.com>; Date: Sun, 9 Oct 2022 09:44:37 +0200 (CEST); You are not required to drive the tube into the grid current region in a Class-C amplifier. The definition of Class C operation is a current flow angle of less than 180 degrees, which is accomplished; /archives//html/Amps/2022-10/msg00014.html (12,108 bytes)

Re: [Amps] Tube Class C operation no Drive power or grid current (score: 1): Author: "Fuqua, William L." <wlfuqu00@uky.edu>; Date: Sun, 9 Oct 2022 19:44:52 +0000; Yes I am very familiar with operational classes of tubes. This is the first time that I have seen class C1 in a spec sheet. And besides that it has about the same efficiency as normal class C2.
