Title: 4-1000 GG Intermod specs
Post by: k7yoo on October 18, 2010, 04:35:28 PM
Awhile back a thread was started about amp tubes--which was well covered and resulted in the posting of an Eimac bulletin regarding GG use of the 4X1. Are there any charts/specs that show IMD products in the GG configuration?

None that Ive seen but some tests I ran years ago show IMD  in the -33 to -40dB range depending on bias settings and over a 3000-6000V range. The exciter was a TS-830S at 110W out on 20M. Some pulls were worse.
