I think with all those the extent of the hazard was not at all realised at the time.
b screws etc from the user. Anything that connected a metal record deck dir ect to mains I don't think would have been legal in the 60s. And by 1970 va lve gramophones were history.
t none quite that bad. Other bare live appliances yes, heaters especially.
as normal for live chassis kit to be properly insulated. A plastic deck was also an option at least from the 60s on.
Bare live metal was really not normal then, outside of heaters, the device in question must have been a very nasty import or some such. Surely no-one would buy such things if they knew it had a 50/50 chance of all being live. You've got to go a lot further back in history to see that sort of practic e under the heading of acceptable.
Sure, but if on a plastic deck the spindle would not be made live. Plastic arms were also the usual, and fishpaper could have been used if a metal one were for some reason fitted.
I can only think that either the appliance was illegal & disreputable or so mething has got mixed up in the memories. 1950s guitar amps with RC insulat ed input were around, those don't normally cause shocks, though of course t here have been occasional deaths resulting from capacitor failure. A setup like that would have been acceptable at the time.
re even worse.
Bowl heaters had a bunch of serious extra safety problems compared to bar f ires. It's why we don't have them today, with the exception of illegal Chin ese imports on dodgy sites.
And talking of safety, I had Clix plugs... even then they were considered i ffy. I did have one worse one though, it had a sharpish prong on each pin, and the pins hinged. Put the flex in, close the pins and the prongs went in to the flex. Yes it worked, but the reliability & ampacity of the resulting contacts were inadequate.
