1. [Amps] Protecting the control grid of a tetrode (score: 1): Author: n2bc at stny.rr.com (Bill Coleman N2BC); Date: Sat May 10 13:43:00 2003; Let me start this over. Typically it is imperative to not apply drive to a grid driven tetrode unless anode voltage is applied. This is usually accomplished by interlocking the T/R switching. I have; /archives//html/Amps/2003-05/msg00080.html (7,461 bytes)
2. [Amps] Protecting the control grid of a tetrode (score: 1): Author: 2 at vc.net (2); Date: Sun May 11 09:13:55 2003; ** In grid driven, Class AB1, there is zero grid current and zero grid-dissipation whether anode V is applied or not. The critical thing is that screen V not be applied unless anode V is present. **; /archives//html/Amps/2003-05/msg00085.html (7,927 bytes)
3. [Amps] Protecting the control grid of a tetrode (score: 1): Author: philk5pc at tyler.net (Phil Clements); Date: Sun May 11 09:14:00 2003; Simple question: Will application of 20 or 30mW of RF damage the tubes when they are not "ready" ?? It looks like the 8122s can handle a couple watts of grid dissipation each - is this relevant if th; /archives//html/Amps/2003-05/msg00087.html (7,343 bytes)
