    I have a set of tubes that are in an old radio chassis that I would like to do something with, The radio is not operational and I think the 7A8 or the 7C7 may be blown, here are the tubes:







    I was hoping to build an AM broadcast band transmitter or something similar. I know there was the knight kit 760 that used the 35Z5 and the 50l6 tubes but I can't find a full schematic that I can work with online.

    I put up a link on your 50l6 thread. (with pics)I know it says 50C6 on that schematic but it works with both. Just make sure the pin out is right. I have my 50L6 TX working now. It is actually pretty decent. Remember much of the circuitry is power supply. There really arent a lot of parts in a CW 1 tube TX. I built the power supply integral. I dont think I would again.
