Wow, what memories this brings back. The only equipment that I have ever
owned that included these was a 1981 Canadian-market electric range. The
last house I had that used these was the old house I had in Canada from
1981-1983, and a new service entrance and breaker panel were some of the
first things I did to the house. My old house in NY City lost these
about 1965--it was originally built in 1921 and had a single phase,
three wire service entrance with two of the 30 Amp fuses as mains. The
replacement had a two-pole 70 amp breaker. I upgraded the 100 amp to 200
amp in my 1984-2004 house in California and the house here came with a
200 A breaker panel.
These are not the best devices, but they certainly were pervasive. The
Fusetron fuses had diameters that were keyed to their ratings, so you
could not put in a different size once you screwed the adapter into the
"edison base" socket (same as a lamp). The adapters had anti-removal
pawls/springs so once the mod was done, it could not be easily undone.
My 1921-built house had fuses in the neutrals as well as the hots!
I'm mentioning this on-list because there are many non-North-American
list members who might have a bit of curiosity about how domestic sound
reproducing equipment received its power--these were the prevalent
protection devices from before the 1920s into the 1950s.
