Has anyone had trouble with speed on their tt

Mosin is right, for the second time in the same thread!

Thanks Mosin but I’m not dismissing any turntable. If users are happy with their Timeline compliant TT that’s great news.
You’ve indirectly summed up my feelings : Everyone should be happy with their TT choice because they chose it. (Timeline notwithstanding).
Let's just say I'm encouraging a little less automatic blanket demonisation of the turntable designing community, which seems to have been an unfortunate consequence of the Timeline Thread.
These issues appear to be taking over the OP’s Thread when it is clear his past/present problems go beyond simple +/-0.02% deviations between turntables or regular and repeatable behaviour of a fully functional power supply?

As an aside, the Rockport Treatise on turntable design was written over a decade ago (and it is wonderful reading). It’s likely that others, apart from us, have read it.
It would be foolish to think that being able to comprehensively describe design problems automatically implies the power to solve all of those problems.
I believe Rockport had a good stab at it (although you'd be struggling to get one now unless you are a millionaire). The new kid on the block – The Beat – is already up to Mk IV/V(?), so it isn’t THAT easy???

Marketing is a powerful tool and Timelines must be flying off the shelves at the moment.
At the end of the day it is just a strobe. An accurate one but a strobe nevertheless. My strobe gets used once then sits in a cupboard for 3 years. (Ok the Timeline is also a record weight but clamps & weights are not always desirable in all circumstances. Indeed, the designer of The Beat claims he tested most of them and is of the opinion that if the turntable design needs one then it is fundamentally flawed(!!)
Granted, that’s only one opinion - two if you include mine – because I’ve always disfavoured them on the grounds that they “stressed the vinyl”, perhaps not quite the same reason/s as his :)
Of course, the Timeline is removable and storable in the cupboard for 3 years. :)

Digital has a perfect timebase but we prefer the imperfect. That’s my core message. (Timelined or not, still crude)
Never thought I’d see the day I’d be using Digital to strengthen an analogue point. :) :)
Nice to see it’s good for something ;) 

Finally, I think some of my Timeline remarks, although humorously intended, were slightly inflammatory, so I owe the lads an apology if the comments caused them any grief.
(In fact I thought the reactions exceptionally kind and polite, all things considered. Hope I will be welcomed back!
All the best....

Dougdeacon is right.

Kiddman says:

Everyone thinks they have great speed stability in their turntables until they hear one that does, then they wonder why the stable one is so clear, so natural, so right.

Which tables have great speed stability -- which are the best out there?

Drubin,

It's a vicious circle. We have yet to define speed stability. There seem to be various camps when it comes to the finer points of that definition.

I'll say this much; I believe it is a relatively narrow field.
