Some of the best electronics-themed
comics appearing in these vintage magazines are the "Radio Term Illustrated"
type - IMHO, anyway. Most of them are ideas suggested by readers, then
illustrators like Frank Beaven created the visuals. The comic on page 79 is
pretty self-explanatory, but the page 66 pun might need some explanation to
those unfamiliar with vacuum tube circuits. The
"B" battery is a
term created by Mr. Lee de Forest as a designation for the second battery
required for the plate bias (the "B") of his Audio tube. Typical voltages were
45 volts, 67½ volts, and 90 volts. If that doesn't completely clear up the pun,
then you also need to know that an alternative definition of
battery which is a
military artillery installation.
