static electricity could be transferred from the old brush bristles to the brush body or handle due to the extremely high resistance. Actually, when I tested the continuity between the bristles and the rotating plastic handle, it read infinity.

I retested the entire old Audioquest brush again, and I obtained 1000 ohms or more between the bristles and some points along the side of the aluminum body. Most of the time there was no continuity along the side, except for the very ends of the brush. Curiously, I was able to obtain as little as 13 ohms if I touched the very top of the aluminum body(top of the U shape). However, a person's hand would never be in that location while holding the brush on the record surface. This doesn't make much sense to me. If the top of the aluminum measures well, why doesn't the rest of the aluminum body measure low resistance. As you can see, I scratched the aluminum body to make sure I had good contact.

Good to hear about the new brush. I'll have to try one out. /nt/ - tketcham 18:44:55 05/13/17 (0)

That would explain why my readings were always fluctuating. My pressure - alaskahiatt 16:12:10 05/13/17 (2)
