1. [Amps] Pulser (score: 1): Author: Edwin Karl <edk0kl@centurytel.net>; Date: Mon, 10 Sep 2012 15:48:37 -0500; The theory behind pulsing when tuning is to tune the radio (remember plate and tune controls) without over dissipating the finals (sweep tubes and even the almighty 6146 included). Works just as well; /archives//html/Amps/2012-09/msg00159.html (6,685 bytes)
