Techinics Sp-10 Mk2a break-in period

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

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

Peter, Does your replacement PS sound better than the original?

Rgds,
