I am working on a board in hopes of determining what component(s) might have failed. There are 3 components that I can't identify and hope that someone might help me determine what they are. The orange component has the following printed on the cardboard sleeve:

Mallory, 12 MFD 200 VNP, 20-47446, 235-7408A

the yellow component has:

105-69, .47/10 250v it is printed on a paper type wrap around what looks to be a plastic core

The purple is a glossy looking ceramic coating on of the says 3 ohms. One of which I know is bad because it is broken and you can see what appears to be some windings around a copper core.



I am sorry for what I am sure are rookie questions but I wasn't able to definitively determine what they are after doing google searches.

All of your images have the sharpest focus behind (or way behind) what you want us to look at.

Having said that, the board is clearly pretty old (maybe up to around 40 years old?) and some parts may have deteriorated over time and not show any visible damage.

Better photos would be great

orange one is a capacitor 12mF 200V max working and am going to guess at non electrolytic as I dont see any positive or nevative markings
yellow one is a capacitor 0.47uF probably either polyester or poly propylene, 250V max working

3 item -- who knows -- as steve said way to blurry to even guess

cheers
Dave
