AOR Japan - that supply is for a radio, right?

Correct. A "communications receiver" so-called, though it's only the size
of a half a shoebox. I'm more accustomed to rack-mounted Racals so please
forgive my cynicism.

That reminds me of the (maybe similar) power supply of another radio.
Last year I bought a Yupiteru MVT-7500. It's a small handheld radio with
a 100 kHz to 1.3 GHz continuous frequency range, operable from either 3
AA cells or an external power supply. It came with a linear PSU, rated
for a 100 V AC mains input (Japanese) and a 12V DC output.

This one is specifically made for this receiver. It even has the pin-outs
for the rx's power socket printed on it. And it's been manufactured for
the UK market. It states 230VAC input; 12VDC @ 500mA output; 12VA rating.
And, "Made by AOR Communications, Tokyo, Japan" under the spec. Could not
be clearer!
