Non capisco come si regola l'antiskating ha un pesetto ma si regola ad orecchio? i manuali non dicono molto

Qui qualcosa si evince. Casomai usa un traduttore. Con il gira davanti potresti riuscire a capirci qualcosa, io solo leggendo non molto. Se riesci facci sapere

The bar and weight method of anti-skating was one method of providing anti-skating – that’s the weight on the right hand side of the tonearm pivot, when you are in front of the turntable. The weight causes the pivoting arm to push the other arm, which is attached to the tonearm, so that the tonearm moves back towards the outside of the record, so that the stylus sits properly in the middle of the groove. The weight on the left of the tonearm is a lateral balance weight which doesn’t need to be changed. 

On some models the anti-skating could be adjusted by moving the anti-skating weight in or out to change it for different tracking weights – the bar that the weight is on usually has marks which correspond to 0.5g or 1g intervals, and it can be slid along that bar towards or away from the pivot, to correspond to the correct tracking weight. From the pics you put up, it looks as though yours is adjustable, although it’s difficult to say as there are no close up photos of the bar and weight. 

Anti-skating wasn’t even mentioned in the Sanyo TP-625 user manual. The tonearm on that model looks very similar to yours, and Sanyo specified the tracking force of the cartridge as 1.5-2.5g, so anti-skating may have been pre-set for about 2g. I suspect that the TP-625/626 (which were the silver and black models) were probably the models below yours – they look similar apart from not having the stroboscope to check speed using the dots on the outside of the platter, which yours has. It shows in the TP-625 service manual that there is a screw holding the weight in position on the bar, so by loosening that screw, you should be able to move the weight. If the bar has no calibrations on it, then the only way of adjusting it would be with the assistance of a test record, such as the Shure ones (available used), or some other similar records, which check for correct anti-skating so that it can be optimised. 

You can download the TP-625 manuals from http://www.vinylengine.com/library/sanyo/tp-625.shtml , although they have no information on setting anti-skating, apart from showing that it exists in the service manual exploded drawings. Obviously the people responsible for those manuals thought it was so simple everyone would know what the engineers were thinking when they designed it!
