1. [Amps] GS-35B optimum B+ for efficiency/power out (score: 1): Author: Patrick Barthelow <apolloeme@live.com>; Date: Tue, 27 Apr 2010 13:05:13 -0700; Since I am designing from scratch, will the GS 35B, like the 3-500Z, produce more power and efficiency at a higher than ham amp-typical B+? Say 4KV? Best Regards, 73, de Pat Barthelow AA6EG _________; /archives//html/Amps/2010-04/msg00670.html (7,010 bytes)
