Turnable database with TimeLine

Dkarmeli, If the KAB locks in at slightly LOWER than correct speed, as you say above, that means my Lenco was running even faster than the KAB revealed it to be, because, as noted, the KAB indicated overspeed, not underspeed. Which means my friend's sense of pitch is not as perfect as he may have thought, since he perceived the tt speed to be slightly "slow". The whole anecdote was noted just to poke fun at ourselves as a group, and the idea that we can perceive tiny errors in tt speed.

It's possible that there would be some minor variation in the performance of the KAB strobe, if there is some minor variation in whatever hardware is used in the strobe to induce it to flash with some exact frequency. Given the nature of such ICs, I would posit that the error there is very tiny, indeed.

Anyone tried the timeline with a Brinkmann table?

@halcro:

> Contrast that to the same Raven AC-2 with the TIMELINE where ‘stylus drag’ is confirmed and differs to the KAB results?

Your test and comparison has a potential fundamental flaw - you must first re-set steady speed with the Timeline and the stylus off the record, before you can make the claim that the Timeline is showing a drift due to stylus drag, that the KAB does not.

The reason that is in your KAB video you have a record weight which is NOT necessarily the same mass as the Timeline, in your timeline video.

A properly executed test will first set speed with whatever device is being tested, with the stylus off the record, then with the stylus on the record.

There is a likelihood that the Timeline itself is actually slowing down the playback, in your Timeline video, not stylus drag.

Halcro, It would really be interesting to see how long my TT maintains the correct speed. Unfortunately I don´t have the devices mentioned available and am not planning to purchase them in near future. Furthermore, I´m not running the Salvation motor in way the Salvation decks do, mine is merely an implementation to a different TT. The motor works more precisely with uber large platters like the Salvation.
And I quite often have issues on mains voltage stability in this remote frontier.
My video wouldn´t do justice to Vic´s magnificent TT.
I would like to see the original Salvation TT in action instead.

Ack, I follow your reasoning right up to the last sentence. The Timeline per se is not even as heavy as the "typical" record weight, and the mass of a record weight/Timeline is concentrated at the center of rotation, where the motive force has a tremendous mechanical advantage, compared to the mechanics of overcoming friction forces applied at the outside edge of an LP via the stylus. Any tt that would be appreciably slowed by the Timeline would be one that is very prone to any effect of stylus drag, as well.

Plus, I may be wrong, but I do think Halcro did the proper control in this case. He will tell us.
