Re: [Amps] GS-35B efficiency (score: 1): Author: "Jim Garland" <4cx250b@muohio.edu>; Date: Fri, 18 Dec 2009 22:07:48 -0700; If builders find that a GS-35B amplifier is significantly less efficient than, say, a 3-500Z amp, then could someone explain why that is so? I always thought that the efficiency is a function of the; /archives//html/Amps/2009-12/msg00476.html (7,074 bytes)

This tube was originally designed as a radar pulse tube and is no doubt optimized for that service, not for linear a; /archives//html/Amps/2009-12/msg00482.html (8,550 bytes)

That might inherent in the structure and spacings in the GS35. S; /archives//html/Amps/2009-12/msg00521.html (7,614 bytes)
