Technics SP-10 TT motor capacitors?

FWIW, While I am an old hand at DIY, I have too many projects and so farmed out the capacitor change to Bill Thalmann at Music Technology in Springfield, VA. Bill is very experienced and way way more knowledgeable than I am. He thought it was prudent to replace them all. We used Panasonic FC types, which Bill likes; they have lower ESR than any that were made back in the day. He is so much more skilled than I and works so fast that the cost was quite reasonable. My Mk2A had been completely refurbished by Technics in 1989 and was never used thereafter. Ergo the lytic caps were "new" but 20 years old. For a unit that has been in constant or even occasional use all these years, one might justify replacing only the bad caps. Unused caps go south quicker. Now I have to go do income taxes, yet another night that I cannot work on my SP10.

Lewm, thanks for the insight. I intend on replacing all and I saw reference to the Panasonic caps elsewhere, so that's the plan. Need to part with the machine long enough to open it up and verify package types/values and get a lay of the land.

There is a certain piece of mind in knowing the lytics are not going to leak and take out an irreplaceable IC. (Most of the ICs in that circuit are no longer made, and some of them were custom built for Technics specifically for that circuit, so not easy to find subs.)

Dear friends: Pryso posted an advise that he receive for someone else: ++++ " if it ain't broke, don't fix it.. " +++++

this is common sense and I'm with.

I can't remember when was the last time that I read elsewhere that cap suffer of a leak or even " exploit " and certainly never from a SP-10 owner.

My whole/general attitude about is to change ( whatever ) parts ( caps, resistors, wire, etc, etc ) in an audio item where we can/could achieve better performance with out an important trade-off.

Of course that for be " peace in mind " and due that it is a very low price everyone of us like to make those changes. No, I don't do it in my SP-10s yet.

I would like to know ( maybe other people could likes too ) from those SP-10 owners that already change the caps/reistors or the like what real changes we can expect/detect with these new parts on the SP-10 quality performance or none at all other that that " peace on mind ".

Could you?: Strathorncat, Lewm or some body else.

Regards and enjoy the music.

Electolytic have a shelf life. It's accepted in the electronics industry. Depends on the application as to how worried to be. Lewm said it well for me:

"There is a certain piece of mind in knowing the lytics are not going to leak and take out an irreplaceable IC. (Most of the ICs in that circuit are no longer made, and some of them were custom built for Technics specifically for that circuit, so not easy to find subs.)"

I just recapped two SH-10E's and found one cap that had broke open and literally leaked. Probably been electrically leaky for years. I guess it depends on how well you think you could recover if a leaky cap damages other circuitry. Not much of an issue in a power supply, but a very unique servo control circuit; I'd rather err on the side of safety.
