I've got the Timeline in house.
On the Lenco, with AC supplied through the Walker Motor Controller, speed set by the KAB with an LP in play, and listening tests suggesting that rhythm and pitch are like real life, the Timeline says my Lenco is a touch fast. I will need another day to determine whether it is "regularly" fast (the error increases in a linear fashion with each revolution) or "irregularly" fast (the error is haphazard in magnitude per revolution). The first kind of error can be "fixed", if I care to do so. The second kind indicates that the Lenco is affected by stylus drag. Not so easy to fix. One red herring: the LP is sitting on a Boston Audio Mat1, which is kind of slippery; the LP itself could be sliding due to stylus drag. I hate when that happens. I hate record weights.
