Hi!

I had a 1960 five -or- six-transistor radio with an optional external
power cord/wire/plug-in device thingy. Matched perfectly with the
input of an immersion coffee re-heater, but that only worked once. :/

Hmm...impressive bang? Lots of smoke? Sudden bright light from within? Sound
output equivalent to a 1,000 watt home theater system but only for a second?
