1. [Amps] Zero Bias Amps Question (score: 1): Author: ko4nrbs@yahoo.com (Bill Smith); Date: Mon, 8 Jul 2002 08:48:31 -0700 (PDT); It has been suggested I add a string of diodes in the center tap of the Filament Transformer in my Swan Mark 1 amplifier for bias. This is a Zero Bias amp but bias is suggested anyway to ensure a sta; /archives//html/Amps/2002-07/msg00124.html (6,901 bytes)
2. [Amps] Zero Bias Amps Question (score: 1): Author: 2@mail.vcnet.com (Richard); Date: Mon, 8 Jul 2002 09:38:28 -0700; 3-400Zs have a Mu of c. 190. They have a ZSAC of c. 80mA each at 3kVDC and 0V g-fil bias. Less ZSAC is ok for CW, but not ok for SSB. - R. L. Measures, a.k.a.
