My First Homemade Super Hetrodyne Radio

Filed under: Electronics — Cranky Sysadmin @ 8:09 pm

Made from vacuum tubes, Woohoo! I built this two tube super heterodyne based on a schematic from Fun With Tubes. The site is pretty amazing. If you want to know about the technical details of tube radios, you could do much worse. It’s also a great place to go for audio tube circuit articles, power supplies for tube circuits, and general “how it works” radio articles.
Why would anyone want to build a tube radio

I probably should post more frequently so I don’t end up with mish-mash posts. My recent projects include;work on a 20 meter QRP rig, helping a friend fix an old military radio, testing a WWII signal generator, and building a one tube regenerative receiver.
