22V batteries (actually, 22.5V) are the same size as 9V PP3 batteries, but they have one terminal on each end. You can still buy them (NEDA 215 or Eveready 412). I built a regenerative 1 tube (1S5) radio in 1958 or '59. It used a 22.5V battery for the plate supply, and a 1.5V D cell for the heater power. That little battery seemed to last forever.blueroomelectronics said:Guess those tubes would keep your head warm. How big are a pair of 22V batteries?
Nice "improved" transistor picture in the article on the hat too.
