And when was it that the beach wear started to be called flip-flops?

I haven't yet tried to explain to my daughter that when I was
her age that flip-flops were electronic circuits.

AFAIK, flip-flops were named in the mid-60s... But I'm sure someone
older will remember that as even earlier!

Weren't 12AX7 flip-flops called "flip-flops"?

ObUsage - that's ECC83 in BrE.
"E" - 6.3 V heaters.
"C" - triode

It's rather fun that it's called "12" and "E" and both are right.

Actually, they were (also) called 'thongs', refering to the toe-wedge.
It would also be misunderstood, nowadays.

Not in Australia. That's our standard name for them.

If you spoke about flip-flops, only those with an electronics background
would understand.

What about "stepped on a pop top"? I don't suppose anyone would get that
anymore either.

I have a pair of thongs without the toe-wedge. (Instead, there's a
couple of velcro pieces that fold over the foot.) Everyone here calls
those thongs too. The name has become divorced from the etymology.

I always called them "sandals".

Those are "thongs" or "jandals" down here downunder.
"Sandals" have extra straps around the heal.

Thongs yeah - but jandals is a Kiwi thing, along with "chilly bin" for an
esky / ice cooler.

And the first digit '8' denoted its B9A base. Only the final '3'
was available to indicate variations on the ECC8* theme.

Eh? Oh, you mean about the series-connected heaters with
a centre-tap so they could be used in series for 12.6V or in
parallel for 6.3V ? I suppose that's "fun" for a certain value
of "fun"

Possibly slightly more "fun" than the dreaded U-
and P- series valves/tubes, often used in low-end consumer
kit, that had a specified filament *current* (P=300mA,
U=100mA IIRC). Allowed the filaments to be connected
in a series string and powered directly from 240VAC
with the help of a huge, hot and unreliable ballast
resistor. Happy days.

The "All American Five" had the filaments tied in series and needed no
steenkin' ballast resistor. There was a little shock hazard in some. Happy
daze indeed.

Well, the wedge-related theme applies either way.

Just as well Otto's kids weren't around in the days of
vehicle battery powered vacuum-tube electronics, then.
The British military (and, I have no doubt, many others)
were fond of using a "vibrator" as part of a circuit
to generate the HT voltage for tube/valve equipment.
It was a kind of self-oscillating mechanical SPDT
switch that could be used to drive a step-up
transformer from a low-voltage DC supply.

To make matters worse, those things usually came
in a cylindrical can about 5" long and about 1.5"
diameter, with a 4-pin valveholder base, and
of course they (surprise) vibrated.... at about
300Hz if memory serves.

This electronics-obsessed teenager was blissfully
unaware of possible recreational uses for such a
device, but I'm sure it was not lost on others.

Did not catch original post; "vibrators" were used in car radios to

step up the 6V battery voltage to 450V in the car radios; some even had
extra contacts for synchronous rectification of the transformer high
voltage - so that a 6X4 or equivalent would not be needed.

I was in the United States Army Signal Corps in North Africa in 1943. We
were in Signal Intelligence, intercepting enemy radio messages. Our
equipment was direction finding receivers installed in two 1942 Plymouth
sedans, "drafted" from the FCC.

They were powered from a six volt battery in the trunk which drove a
"vibrator" power unit which supplied 120V AC to the receivers. The
battery had to be charged often!

These vibrated at about 60 Hz, but it was confined to the internal of
the device.

Early automobile radios using such a device were very common.

being the field coil for the speaker

The 'vibrator' marked component in the original referenced
comic is shown as a motor symbol; that's the pager/cellphone
type of eccentric weight vibrator. It's clean; one end
is wired to the moral rectifier.

No no - not "xor", "zor". They're also called zoris.
