Turntable speed accuracy
Sometimes there is simply no substitute for the ears?I had recently switched from the original rubber belt of the Raven AC-2.....to a thread drive.There was little difference in the speed consistency as shown by the Timeline......but initially.......

Hi Dover,It's a running joke between Lew and me.Albert got it.......so did Hiho :^)

Good news Lew,But are you sure the Timeline is accurate? :^) 
Cart recommendations for Fidelity Research FR-64S
I have both the FR-64s and FR-66s and use the FR-7f, Dynavector XV-1s and ZYX UNIverse for LOMCs.....but then I have about 20 other vintage MM cartridges. You can look on my Systems Page :^)

Congratulations on procuring one of the great arms in analogue history.Changing headshells is a breeze and whilst some find the original FR headshells very heavy......I find that they mate well, especially with the heavier LOMC cartridges out ther... 
Timeline Calculator
It sounds great Ketchup.The only problem I can envisage......is the difficulty of positioning the laser line 'dead-on' the centreline of the spindle and at right-angles to the wall?It is difficult enough to just position it somewhere behind the tu...

Hi Tony,I'm not into the maths :-)I'm simply quoting the read-outs on the digital display of the TT-101 as I change the pitch in 6Hz increments.Perhaps someone can help with the correct calculations? 
Who needs a MM cartridge type when we have MC?
It is my subjective opinion, yes, that carbon fiber does not make "music". I tend to agree with Lew on this one.IIRC....didn't Lloyd Walker design a carbon fibre arm for the Proscenium?This iteration did not last long and was replaced by a ceramic... 
Turntable speed accuracy
Thank you In_shore,But what happens if the orchestra being recorded is already tuned 12Hz lower than 440Hz which means that at 33.33rpm......we are getting 428Hz for the note A?If our turntables are then running slow by....say 12Hz.....it can't re...

Dear Swampwalker,Please look HERE

Sorry Tony,Whilst I measured the distance from the turntable spindle to the wall at 350mm at right angles.....the laser line was actually projected approx. 400mm from the spindle to the wall at approx. 30 degrees.Everything I said was approximate ... 
Turntable speed accuracy
Hi Chris,My statement was directed at the 'speed' of any correction performed by the motor controller being felt by the platter?I don't think there is any doubt that in a DD situation with the platter being attached to the motor......any speed cor... 
SME speed adjustment
Of course you're both correct :-)The distance from the spindle to the wall in my example above.....is 350mm.The problem with stylus drag is that one doesn't consciously hear it.From all that I have seen, read and heard over the last 6 months.........

You may be worrying needlessly Peter?It is not necessary to have the turntable revolve at precisely 33.33rpm to have good sound.Orchestras around the world don't always base their pitch on the note A being at 440Hz. Anywhere +or-12Hz in pitch is q... 
Turntable speed accuracy
Regardless of what the speed inaccuracy is due to.......one must find it and correct it as it is distortion of the analogue sine wave...pure and simple.The Timeline will show it....and you must correct it. Not look for excuses :^)
