It's been a while
since I posted a new set of electronics-themed comics from vintage magazines.
These three appeared in a 1964 issue of Radio-Electronics. The page 37
comic shows the wife asking a presumably inane question, but in fact there were
duo-whatever vacuum tubes that were the inclusion of a pair of single tube
types, usually with a 12.6 V heater voltage. A well-known example is the
12AX7, which is essentially a
pair of 6AV6 triode tubes. Besides that, there was both a
6SN7 and a 12SN(X)7 tube, the
former with a 6.3 V heater and the latter with a 12.6 V heater. Here's a question for
you: What is that thing on the floor to the right of the box of vacuum tubes in
the page 37 comic?* The page 72 comic is not so
far-fetched. I have no doubt that somewhere in the world - multiple places and
times, likely - people have heated or cooked something in front of a microwave
communications dish.
Electronics-Themed Comics
"No 12SN7, Dear, How about two 6SN7's instead?"

"No, it's not a printed circuit, I backed over it in the garage."

* Answer: Probably a screwdriver, but possibly a tube puller.
These Technically-Themed Comics Appeared in Vintage Electronics Magazines. I
personally scanned and posted every one from copies I own (and even colorized some).
272 pages as of 12/16/2025.
