Hi Tubes,
I have spent alot of time on this the last few days. Through trial and error while spinning alot of LP's I have come to the conclusion that all is well with the Vector. Once I thought I had solved the issue when I grounded both the bearing and the arm to the same ground lug on the phono stage. I also noticed that I had threaded the bear wires through the hole in the ground stud so that when I tighted the cap it was crimping and cutting the wires. So now the wires are just wound around the post.
All was well until I used the AQ brush on an LP before playing. Immediately the pop was back and there were several during the first half of the first track. Then things quieted down. I then tried just a couple of quick swipes with the brush instead of holding it for several rotations like the instructions say. Only one or two pops of significantly less intensity. I'm going to try to figure out a way to ground the AQ brush and see what that does. It is a great tonearm and I love the sound produced by it and the 103R. My plan is to upgrade to a higher performing low-compliance MC, like a Shelter 90X, once I get this issue solved. I'll have to keep playing with this to really convince myself that this is what is happening. Several times through this I've thought that I had the answer only to be proven wrong.
I agree 100% with your assessment of A.J. Conti. He has helped me out several times and is always quick to respond to emails. Now that I feel that I have a handle on what is causing this problem it does make sense to see if he thinks it is worth having a look at the wires on the tonearm. What I have found with the application of the AQ brush may be exposing a problem in the tonearm wires. They are close enough that I can hand carry the parts to them. A great excuse to visit a used LP store I know of that's on the way over to Hollis.
Although frustrating, it has been a great experience. I've learned alot more about adjusting both arms and now I have this nifty little fixture to support either tonearm when it is off the turntable. I see a multi-arm 'table in my future!
