Turning 50 years old

Turning 50 years old

Pulled a couple ballasts today with date code KD, 1968. One was shorted, unfortunately, but this one works. The wires are brittle and crumbly in places but it can be fixed easily enough. Thought it was interesting since it turned 50 this year.

Is this also a cold temp ballast? I've got cold temp GE Bonus Line rapid start ballasts that have
this same shape to them, without the slanted edges that most high power factor rapid start ballasts normally have.
I've also got one Magnetek cold temp version that also has this same shape.
Also, what exactly does a ballast do when it shorts? There was a strange phenomenon that occurred with several
of my GE Bonus Line cold temp ballasts... I wonder if what I was experiencing is the same as shorting?

Interests:
1. Motorcycles, cars, Women, and Lighting (especially fluorescent)
2. Weightlifting/staying extremely athletic
3. Severe Thunderstorms of all kinds
4. Food and drinks. So gimme them bbq ribs
Lighting has ALWAYS been a passion of mine. I consider everyone on here to be a friend

Good quality things are awesome. Cheaply made things are not.

Not a cold temp ballast, at least there is nothing to indicate that. I think this shape is just an earlier design than the slanted edge version.

The shorted ballast drew a a bunch of extra current and put 120v to one of the filaments.

I think what often causes that is the internal capacitor shorts, causing the ballast to work normally but draw extra current. I have a few that are in this stage. The ballast runs hot and maybe trips the thermal protection or maybe not, eventually the insulation on the winding's fails from the heat. Or at least that is my theory.
