9/97: This is a PC board lashup of a 6DQ5 CW transmitter for 40M. I never transferred the design into a box; in fact, I don't recall writing down the details of the circuit. Worked well, and put out more power than a 6L6 in a similar circuit. The power supply in a galvanized iron box is also home-brew, and put out 440VDC plus AC filament feeds.
