I almost bought a Teres, but seeing how much adjustments one had to do as every LP was played, broke the deal.
I have no idea what this is supposed to mean. I have used the same mylar belt on my Teres for about two years and have never had to adjust it in any way.
Belt slips= timing inaccuracy. Must then readjust belt, or string.
Again, I've never had to do this over two years of regular use.
