@boothroyd Thanks Dave. You've been helpful the many times I've posted. I can do as you suggest but I fail to understand 'I believe you’ll see it hunting along the taper causing the pitch deviation.' Would you please clarify?
Meandering Pitch, Where’s The Problem?
As I’ve mentioned in other posts, I’ve been modifying a Thorens TD 160 MK1. It is and will remain a dedicated mono table. Currently, I’m using the original TP 16 MK1 tonearm with an AT 33 mono cartridge. I will eventually replace the TP 16 with an Origin Live tonearm and EMT mono cartridge. I still however like playing records while in it’s current state. What I’ve experienced with a number of classical records is pitch instability. Primarily when playing piano recordings. There are certain passages that are a problem and I’m not exactly sure the cause. My cartridge is aligned using Baerwald. I understand that with some records, especially very old mono vinyl, that the pressings could be off but if that were the case, then the entire album would be an issue. I do need a new belt but I’ve still had this issue with a brand new Thorens or Origin Live belt. Just wondering what others think and if there’s an antidote? Thanks!

@oddiofyl Oh sorry, I mistook you for Dave. So what’s the antidote? If it’s tension then wouldn’t a new belt resolve the issue? I can say that the Origin Live belts are wider than the Thorens belts so I gently widened the metal hook next to the pulley that rises and lowers the belt to 45 and 33 &1/3 but the belt is unobstructed there either way. @fusian yeah but I have the same problem with a Speakers Corner Glenn Gould Beethoven reissue. |
Great advice from everyone. My thoughts regarding the spindle hole is that wow would be present in more than one or two spots if it were the cause, though I admit I don't know this for sure. Now regarding the pulley, there is an upgrade replacement that I should consider. Nevertheless, buying a new belt will be the first thing I do. |
