Click to expand.I just seen your post on the Henry 2002 amp and I have one. I also have a a couple of the 6N2 amps amps. Henry did short run builds and they can be different. My 2002 has the 2002 on the face plate, it has the built in T/R relays and a 2 meter low pass filter on the output mounted on the back of the tube screen. They left out the 6M circuits and the input is different even different from the one that was in the 2002 manual.
QEX July/August has an article on building a 6&2 meter amp like the Henry 6N2. Hi Jim, Were you looking over my shoulder!? I've not had a chance to do anything with the 6N2 for months until today, and seeings as we have snow limiting movements, I've just dug it out the pile of todo's and started cleaning it up and listing parts needed. Understood regarding differences and short runs. I'm also lead to believe, the 6N2 had unwanted harmonic tendances on the band not in use and may have lead to the changes with the design when the new range became available. I'm going to keep it as it is and just use on 2m, and will make other arrangements for 6m from the junk shed.
This is the manuals page for Henry Radio. In this page you find schematic, users and instructions manuals, service manuals, technical supplement, leaf leads and other good stuff. Tempo-6 N 2 Operating and maintanance manual.zip.
Thank you for message Vy 73 Chris G1rpo.
Hello Tom, You've provided some information on your Tempo 2006A 6 meter RF amplifier as far as the Grid and Plate Currents and RF Drive but you haven't provided the Plate High Voltage DC reading. I see you've got a later version 2006A amplifier using a single 3CX800A vacuum tube in the Ground Grid configuration. When Henry Radio first started selling these High Power RF Amplifiers in the 1970s, they started out as Tempo 6N2 using a pair of 3CX400A / 8874s and capable of covering 50-54 MHz and 144-148 MHz using the Ground Grid configuration on both bands.

Henry Radio had to stop manufacturing the 6N2 because it did not meet the current FCC emission standards on 6 meters. Henry Radio then came out with the Tempo 2000 Series Single Band RF amplifiers: 2006A 50-54 MHz, 2002A 144-148 MHz, 2003A 220-225 MHz and 2004A 430-450 MHz. All of these were Ground Grid and used a pair of the 3CX400A / 8874s vacuum tubes. Into the 1990s Henry Radio set up Radio Dan to start manufacturing these same RF amplifiers but using a single Svetlana (Russian Made) RF vacuum tube which are High Mu (Gain) which would cut the manufacturing cost, not required neutralization and produce the same RF Output for a given RF Input Drive. I really believe to produce 1200 RF Watts Output on the Tempo 2006A, you would be required to have 40-50 RF Watts Input Drive. There's another observation I've made, 'if' your RF Input VSWR is above 1.3:1 or higher you will develop Positive Grid Current in Classes AB1 and AB2 Linear Operation so keep the lowest VSWR between your Transceiver and the RF Input on the amplifier. Another item I've noticed with the Svetlana RF vacuum tubes is the Filament voltage.
