Brown, black, yellow, gold is 100k
And here's a chart showing that. It also shows that the gold band indicates +/- 5%.
Brown is 1, black is 0, so that makes 10. Multiplied by yellow, which is 10K, makes 100K.
But I prefer to measure with a meter. Especially with 5% tolerance parts, it can be interesting and informative to find that the values of two "identical" parts are significantly different but within tolerance. Ruling out soldering mistakes, this can explain why the voltages on one channel are slightly higher/lower than the other. I used to be perplexed by such voltage differences, figuring I had a bad joint somewhere that was adding resistance.
