One night, years ago, running the homebrew Henry saw the plate voltage meter against the peg at 4000. They told me it was within 10% tolerance. 240 x 1.1= 264. Walmart light bulbs would last a day.
I guess the guys designing the Collins S Lines, forgot to check with you, before they used 115/230 volt primaries. My Henry 3K-A book says 230 V The Henry 4 K says 230. ? ___________________________

There are a bunch on notes and papers on the Eimac site. Its been some time since I looked through them. Stuff about operation at reduced filament voltage, for longer life, but dont remember anythin

While we are dancing with coax, and I don't have the original post, was the SWR always bad or did it just go bad. Looking at the Titan 425, it has a "lowpass filter" board, as in tuned input, with a

What was Collins doing in the 30S1? I thought they did the same thing in the 30L1, but dont see any circuit. I looked at the S1 manual, and see some transformer on the schematic, but have yet to fin

Google all the Eimac papers. Care and Feeding, etc.. There is stuff about reducing filament voltage during standby and during operating. _______________________________________________ Amps mailing
