Hey Ron & Others
I placed a mirror under the mech in the tone arm area. Yup, I could then clearly see the wheel I needed to turn to make the adjustment to balance the tone arm. Now that I knew what I was looking for, I coud see some of the wheel from above, which before I thought was part of the counter weight.
Really very simple when you know what your are looking for and how to locate it.
The skating issue has now been resolved and thanks to all for their assistance and patience.
Best
Darrell
