The simplist and safest screen supply is a zener-string shunt regulator at the lv end of the hv bleeder. 40, 5W, 20v zeners mounted on perfboa; /archives//html/Amps/2002-11/msg00387.html (7,689 bytes)

[Amps] Passive grid: (score: 1): Author: garyschafer@attbi.com (Gary Schafer); Date: Thu, 28 Nov 2002 20:26:24 -0500; Hi Rich, I have always worried about using a zener string from the HV supply for the screen. What happens if the plate choke or something else should open in the plate circuit? Also if one were to tu; /archives//html/Amps/2002-11/msg00393.html (7,147 bytes)
