The "Sky King" Solid State Regen Radio
On October 8, 2014, a guy named Greg emailed me out of the blue. He included seven attachments in the email. Some of them were plans for a regen "Twinplex" radio from a Lindsay publication. He wrote "Enjoy, let me know how it works out for you." I didn't get around to playing with the circuit 'til the middle of January, 2015.
Power Amplifier Tube datasheet in Retro Style
Finally, I finished working on a datasheet, in which I decided to combine the most popular amplifier pentodes and tetrodes. I decided to make the design in the style of old radio magazines from the 1960s in several variations - two in the style of old paper and two in the style of inserts from the magazine (color and monochrome). The design itself was not complicated, but collecting the information itself made me sweat a lot while I re-read the specifications for each radio tube listed here.
