As I understand it, you are at the step of installing the 1Kohm resistors that bridge the Left and right RCA output pairs. If they are the 5 color band resistors as in my kit, the color bands are brown, black, black, brown, brown and you should have two of them. Knowing the colors and then following the advice of Vetmed and Grainger, you should be able to experiment with your meter as suggested and measure them as 1Kohm (1000 ohms). Your meter will probably not read them as exactly 1Kohm. It may measure in the high 990 ohm range or it may measure them slightly over 1Kohm. And depending on your meter and the ranging, if they measure slightly under 1Kohm it may read out as .998 K or as 998 ohms for example. My point is that you can visually identify the resistors by color band and then take the opportunity to verify with the meter which is good practice anyway, and will get you familiar with the meter. On top of that, sometimes it's hard to tell what color you are looking at. For example, purple can look brown. So always good to know how to use that meter. The clip lead idea is very good, and a good idea to pick up a set. But if you dont have a set now, you should still be able to get a measurement by using your fingers to hold the resistor leads to the meter probes.
Here is a good link to a calculator that allows you to plug in the color bands and tells you what the value is ...
