## Questions & Answers

**Q: It says type B10 (10K) but the text says 500k. Which is right?**
A: They are indeed 10K.. or approx..  I just got my multi-meter out and tested both of mine and one was 8.94K and the other was 9.4K.. close enough unless you are doing a serious audiophile project. Pretty much what you can expect when made from the finest Chineseium available on Amazon   :) Hope this helps

**Q: What's the rotation angle on these? Is it 300 degrees like typical pots?**
A: Yes 300,degrees as typical pots do.

**Q: What size nut does this pot use?  Need  to know what size hole to drill in the chassis**
A: The inner diameter of the nut is 6mm.

**Q: The are two lugs in the back for switch. How to tell which one is positive and negative?**
A: A switch does not have a positive or negative.
