I am trying to figure out the values of the cap and resistor in this picture:

For the cap, 224J means 224uF, correct?

For the resistor (I know the color is not great in the picture) I read: Green red purple gold. But this comes to 520 million ohms +/-5%, which can't be right. Am I reading that reversed? If it is reversed, it is gold purple red green(or brown maybe). But what does gold mean as the first band?

I think the 4 at the end refers to the number of decimal places (can't remember the exact meaning) but I think that makes it .22uF. Can't help you on the resistor.

The caps look like Panasonic's 0.22uF metallized polyester film capacitors, 250V, type ECWF(B), 5% tolerance

thanks for the help, Joshatdot.

get a cheap Craftsman DMM with capacitance and resistance and you'll never have to worry about this again. I never tried to figure out those damn color codes for resistors, they're too confusing.

The purple stripe might really be brown not violet? That's my guess, 520 Ohm. Gotta agree with PinkFloyd4Ever though, a meter measurement is a good idea.

It might not be a great idea ot use a multimeter to determine part values when they are already soldered into a circuit. Other parts within the circuit could be in series or parallel with the measured part and could throw off the reading.

That looks like someone added in a Zobel network, kind of unusual in a headphone amp. Film and other types of small value capacitors almost always give their values in pF. The last number would be the number of zeros, so 224 is 220,000pF, or 220nF/.22uF as it's already been pointed out.

Google image search turns up a bunch of useful resistor color code charts. I'd guess 520 ohms too for that resistor.
