This article is in the 1980 ARRL Handbook, showing a grid-driven 833A in linear service. But I have never heard of anyone actually trying it, and I've done many Google searches. http://www.w7ekb.com/
One of my first linears back in about 1960 was a grid driven pp pair of 833A I used four 6CL6 as driver for my CE 10B When it spoke it had a loud voice. Paul K0UYA -- Original Message -- From: "Mike
Yea, Paul, I'm sure it gave the CE 10 a loud voice. I'd like to see your driver circuit. Let me attempt to fill some blanks about your amp. Hmm... Push Pull, amplifies both halves of the cycle, low d
Jim Driver was just (4) 6CL6 in simplest GG form. Filament volts, Plate volts, about 600 I recall. RFC on the un tuned input and pi net out. It was my very first linear The 833's were pp in and out.
Shoot, what you have described sounds like a damn fine piece of gear and way better than the "consumer ham" cheap stuff manufactured today. Too bad you don't have it still. It could probably sit ther
I appreciate all of the replies, both on and off the list. K0UYA is the only one who replied who ever built one. 73, Mike www.w0btu.com _______________________________________________ Amps mailing li
Its not a very linear tube for SSB, great for AM. Carl KM1H I appreciate all of the replies, both on and off the list. K0UYA is the only one who replied who ever built one. 73, Mike www.w0btu.com One
Well, two grid-driven 833Cs in parallel may or may not be as linear as the best expensive ceramic triodes in G-G. But if it's linear enough not to make my signal much wider, it's good enough for me.
You will need a push pull type of grid circuit in order to neutralize them. The bridge type circuit will not work well. If you just swamp the grids with a resistor and use a step up transformer it wi
Performance will be similar to a 250TH or any other large glass low mu 1930's tube used as a SSB linear. Low mu by current standards anyway. Expect IMD in the mid to high -20's which is right in the
Gary (et al), How about adding a tertiary winding to the step-up transformer, and use that for the out-of-phase neutralizing signal? One end of the winding to ground, the other end to a neut. capacit
