Continuing on my newfound obsession with Thermatron's (vacuum tubes) for your dining and dancing pleasure I present the 5763 miniature CW transmitter operating on 40M with two watts of output.
The 5763 has been around for a long time and circuits abound on the Internet and for those who paid an exorbitant sum for a digital copy you can find the schematic in QST's of the past.
I know ad nauseum but there is at least one more home-grown rig in the queue beyond the 5763.
Sit back, relax and enjoy.
