Back in the 60s, a couple of TV manufacturers used fusible links to protect the filament string. I don't remember the diameter only that we had a small roll of enameled wire of the correct diameter just for this purpose. A suitable size was cut, tinned, sleeved with a fabric tube and soldered between two terminals.

I don't recall why this was done as opposed to using a glass pigtail fuse or socketed fuse for that matter.

Any recollection of which manufacturers used that method of fusing?

Snort... "recollection"? I wear a name tag so I remember who I am. But I KNOW my older brother will remember not only who used it but what gauge of wire as well. I'll post back later today.

I talked to my brother yesterday and while he remembers the wire fuse, he doesn't remember the manufacturer(s) either. He thinks it was used as line or B+ while I think it was filament protection. Just too long ago.

If Lenny is looking in, maybe he will remember.


Wire fuses were used in old mains fuse boxes, where wire was located
between screw-down terminals in a removable shielded plug assembly,
with isolated finger pull tabs. Basically a fuse assembly with
replaceable fuse link. Too easily defeated or misapplied with
non-standard fuse wire, and a source of combustion.

You can still buy "fuse wire" in the UK. Google it.
