Techinics Sp-10 Mk2a break-in period

There is ZERO break in on these parts, think about it, your table either hold speed or it does not.

Good listening

I would have to think that there definitely IS a break-in period for an entirely new tt bearing system, of most types. This would vary according to the nature of the bearing (there are many types) and the materials used in the bearing system, including the thrust pad (ditto). What you might hear during break-in is slightly more noise than what will be the eventual norm. Most likely, the variance will be from "no noise" to "even less noise". So, forgeddaboudit.

Dear Peter,

I read somewhere that upgrading the stock power cord on the power supply made improvements to the sound. If that is indeed true, swapping out all the 30+ year old caps should also have an effect on the sound. Thus, my reason for the question.

Dear Lewn,

Your point is well taken. I would imagine the mating surfaces between the thrust pad and bearing can take some time to "get along".

Norm,

Absolutely no question that replacing 30 year old electrolytic capacitors is a great idea - however the "break-in" of these will have no effect on the tables speed stability. As far as bearing breaking in , as Lewm puts it going form "no noise" to "even less noise" will probably have very negligible effect also :-)

In addition to the GrooveMaster Vintage Direct I've also been working a little on the SP10Mk2 and have made a completely new stand alone power supply for these should anyone be interested.

Good Listening

Peter

So in short, to answer the original question, the answer is 'almost nothing to no change at all'.

Really the point is that it will likely keep running the way it had been for another 35 years...
