Audible wow on Well Tempered TT

@lewm 
Ehhhh,
OF COURSE! and very much meant, the stylus IS attached to the cantilever!!! 😏 

AND OF COURSE still nicely tracking, following the record groove also! 

The stylus AND cantilever! VISIBLY moves about, deflects visibly, laterally, from the cartridge body, via it's suspension, no doubt. 

This cantilever/stylus deflection, pretty much is in consort of the wow heard - and given due to the described 'tonearm' damping via anti-scate force setting and/or silicone etc. damping trough (this given the high 40cu compliance) 

Please don't expect me to write a Phd theses on this now, please! 😊 

Not THAT hard to understand now, I think. 

If the compliance is a lot less (than 40cu, ~ <= 18cu) - 'visibly' - the tonearm, cartridge en complete, moves just fine with the off-center displacement, with no *visible* defection. 

I hope this will make it a bit more clear, if needs be? 🤔

@lewm 

Oh, and one more thing, you are seriously suggesting an e.g. 40cu compliance will only apply vertically ?!? 🤔

Looking/feeling the Ortofon M20 E super or FL super (stylus+cantilever) inserts does not convince me of that take, at all - as it is pretty 'wobbly' left to right, too to bottom... compared to the e.g. ORTOFON CADENZAS BLACK of less than half that Compliance ~ 18cu.

I don’t know the WT decks from back then. What is the belt made of, I assume it’s not like the current WT decks’.
I had a similar problem with a Townshend Rock Mk2, which uses a round rubber belt, basically a 1/16” cross section O ring. After fitting a new belt there was speed instability noticeable on piano music. The belt was taking a set when it cooled after use. A belt direct from Townshend was the same so I ended up going back to a 10 year old belt. I’ve since replaced the Rock as my main deck but it still gets occasional use for mono, I remove the belt from the pulley when I stop it for longer than the time it takes to clamp another disc.

Off center records, no good.
