Turnable database with TimeLine


Here is a database showing various turntables being tested for speed accuracy and speed consistency using the Sutherland TimeLine strobe device. Members are invited to add their own videos showing their turntables.

Tonywinsc, Hey, me too! It's also interesting how far you can go with plain old digital, regardless of what the digital designers have in mind. Lol
In agreement with Dover: Not only would one have to adjust the controller for each LP, but one would also have to leap out of one's seat to adjust the controller during highly modulated groove passages and then again when the music has smoothed out. I saw this very phenomenon whilst observing the Timeline on my friend's highly inaccurate belt drive tt (in fairness, later shown to have a malfunctioning motor controller). He had to run up to adjust the controller about every 30 seconds, in an attempt to quell the travel of the laser dot in one direction and then the other, across his listening room.

In disagreement with Dover: It was very unfair of you to indirectly accuse Richard Krebs of plagiarizing Moncrief (who is a scoundrel himself but in other ways). What Moncrief wrote, and what RK wrote, about tt speed as a determinant of musical accuracy, is self-evident to anyone who thinks about it. And RK did not claim to be the first to frame this obvious point. One may as well say that claiming the sun will rise in the morning is stealing from Copernicus (one of Halcro's favorite people).

Further, it's "copyright", not "copywrite".
Ketchup, I'll take you up on your offer. How do I get my email to you so that you can PM me? Thanks.

The only way to contact someone through Audiogon that I know of is to click "Learn" then "Member Directory." Look up the person you want to contact and then click "Send Message." I'll send you a message now.

Doesn't this discussion on DD servos highlight the question, does a very high mass platter, with very high inertia, driven by a high torque motor with a belt, thread or fluid drive with built in slippage, such that the platter mass will drive through any load fluctuations sound better than a DD with its constant speed correction.
Dover,
Perhaps your memory is fading?
You have mistakenly attributed the following quote to Richardkrebs.
No,,,,,I was responding to Richardkrebs answer to Don_c55 about smearing of the soundwave due to speed fluctuations.
If you...or anyone else thought that quote was attributed to Richard....my apologies.
I communicated directly with Peter Moncrieff and obtained his permission in writing prior to posting his entire article on these Forums nearly 3 years ago.
Perhaps you even read them here at that time?
