The heck is this?!?
GadgetBoy:
Pinkish resistor with red, red, gold, gold, white (or vice versa - doesn't make sense either way).
Any thoughts?

I ddon't know a lot, but my best first guess would be some kind of old axial lead capacitor. Paper wound. But the board says R10. Makes no sense.
If you have a ESR meter you may want to try it and then see what the DC resistance (and continuity) of the part to help find out.
What is this in?
tooki:
I think the pink denotes a fusible resistor. (As in, not all fusible resistors are pink, but if a resistor is pink, there's a decent chance it's fusible.)
floobydust:
The first four bands are the usual IEC: red red gold gold = 2 2 x0.1 ±5% gives 2R2 ±5%.
The fifth band is open season, unfortunately (resistor) manufacturer specific.
These have a safety function because they burn up when something else fails short circuit.
It would be a flame-proof fusible resistor. But I am not sure who made it, i.e. Yageo, KOA, Welwyn, TT, Futaba etc.
Fifth band:
White: fusible
Gold: miniature fusible (usually with pink body)
Yellow: "constant voltage fusibility"
Black: sometimes wirewound fusible resistor, but I see film types too
Violet: Vishay NFR25H
Some series use coloured fifth band to denote fusibility overload rating (4x,8x,64x).
xrunner:
Or use the brute force method - unsolder one end and get to it with a DMM ... :popcorn:
