Techinics Sp-10 Mk2a break-in period


I recently had all the electrolytic caps, thrust bearing, and bearing replaced on my sp-10 mk2a TT and PS. I like to know if there is a break-in period for these parts. If so, what sonic changes should I expect during the break-in period. Thank you.

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...
There are other reasons besides speed accuracy why things like capacitors and solder joints need to break in. Can you not hear? Hel-loo!
Geoff,

No audio signal passes through the power supply and control system of turntable motor system - its ONLY task is to maintain the correct speed.

Good Listening,

Peter
