It has great potential to outlast its owner! This topic; /archives//html/Amps/2000-04/msg00108.html (8,853 bytes)
284. SV: [AMPS] Inrush Current (score: 1): Author: Ian White, G3SEK" <g3sek@ifwtech.com (Ian White, G3SEK); Date: Wed, 26 Apr 2000 18:18:12 +0100; An external B+ to ground short in a GG amplifier - the classic case being powering-up with the B+ crowbar switch closed - will not send any current through the cathode at all. The current flows back; /archives//html/Amps/2000-04/msg00157.html (10,342 bytes)
