1. [AMPS] 3cx1000a7 bias (score: 1): Author: apight@pa.net (a.p.); Date: Sun, 18 Jun 2000 09:40:28 -0400; Hello, I am building a 6M amp and currently deciding on a bias switching scheme. I note in the SB-220 they use a rather high resistance in the zener bias circuit and switch the relay from the 110 (or; /archives//html/Amps/2000-06/msg00234.html (7,039 bytes)
2. [AMPS] 3cx1000a7 bias (score: 1): Author: 2@vc.net (measures); Date: Sun, 18 Jun 2000 10:47:53 -0700; Zeners are not adjustable. They usually don't survive a glitch. A string of foreward biased diodes is Way cheaper than a zener and they are adjustable in 0.7v steps. // With V-cutoff bias, there is; /archives//html/Amps/2000-06/msg00241.html (7,664 bytes)
