47k 2W (probably) carbon resistor
10% tolerance
High stability

Well - that's what it looks like to me!

It's a capacitor.. Yellow band is band 1.

A molded-case capacitor? The code bands look old, and capacitors made
since (at least) the 1960's have been printed, so I'd guess one of the
last paper capacitors, made after the switch from waxed cardboard to
molded plastic cases, but before polyester film dielectrics replaced
paper. The first three bands (from the right) almost certainly mean 47K
(picofarads), or .047 microfarads. The fourth and fifth bands will be
some combination of tolerance, temperature coefficient and voltage
rating, but I don't remember which.

It is an inductor. The type we used to see in a ceramic glazed modern
version on say... an old trident video card.

Why doesn't somebody measure it. Most multimeters nowadays do resistors,
capacitors , inductors....don't they? Surely a friend must have one? No?

It's a paper capacitor. 47 3(multiplier) µµf, black band is tolerance -
+-20%, red band is voltage - 200V

MIL standard MIL-C-91A

I believe they stopped making these in the 50's

If it still had its original specs then it wouldn't have been necessary to
remove it. Yes?

And the group says (drum roll please) it's almost definitely, a resistor
or a capacitor or an inductor. ;-)

Chances are, the original poster probably though it
was a resistor, tried to measure it.. only to find it
open... Then probably tried to replace it with a resistor
and let the magic smoke out of the replacement and maybe
a couple of other parts. It's not a resistor, It's not
an inductor... It is a capacitor.

I think he knows what it is, he's just giving the group a quiz.

It looks like a Sprague 'Black Beauty' capacitor, which has a fair
amount of inductance from the way it's wound, and they turn into a
resistor as they age. They were a standard paper and foil capacitor,
impregnated with transformer oil and molded into a plastic case.

Oh for pete sakes!
You got a photo and decided it was defective , what ever it is...
get a meat cleaver and chop it once to see whats inside and you will know.

Good luck
