This is a first draft of a notional view of a no-tune broad band (Not Ina Rae Hutton) Linear RF Amp stage. It is hoped with the low plate voltage on the 12GE5 to see about 20 watts PEP.
A board has been cut for the Driver (12DQ7) and the Final (12GE5). A pair of 6GE5's in the Heathkit Monoband radios got you 100 watts. The board is hot off the CNC and needs a cleanup and making the penetrations for the relay and tube sockets still need to be done.
With the 12DQ7 and 12GE5 this will replace the solid-state stages in the Hybrid rig and will make it closer to a full tube rig. There will be shielding between the stages. The 12DQ7 will have a Band Pass Coupler to the 12GE5. (Lower right-hand corner are the coupler pads.)
Them that know can make it go!
