Technics SP-10 TT motor capacitors?


Hello, I have just recapped the SH-10E power supply for my SP-10mkii (8 total). Are there other caps on the TT electronics or motor that will need to be addressed, as well? Thanks for any info.

Hi Strathorncat:

I'm just about to order the eight electrolytics for the power supply with my SP-10 Mk2A. What brand did you use and did you have any problems with size fitting the board?

I assume you have the Service Manual for your Mk2. If not, you can download a copy on VinylEngine. You might want to check again, I count 25 electrolytics on the Main Unit Section of my Mk2A and it was alleged to have a simplified circuit compared to the Mk2.

I'm also on the fence on replacing the 'lytics on the Main Unit. Talking with a few friends who know a great deal more about electronics than I do; one recommends replacing all electrolytics over 15 years old, a second recommends it would be OK to do just to give me peace of mind, while the third says, if it ain't broke, don't fix it. That is why I'm still firmly on the fence for making that change.

Have you built a plinth for your SP-10 or do you have a Technics or other manufactured plinth?
Some references on questions ask here:

Raul, I've wondered too about the potential for "improved" performance with tt parts replacement versus piece of mind from eliminating old parts. Albert Porter who is well known on A'gon for his rebuild of his SP-10 Mk2, chose to upgrade caps in the power supply but left his motor unit alone. And while this is not the same for a turntable where the parts are out of the signal path, my friend Dan Banquer posted this description of sonic benefits from parts replacements in a tuner.

Now for Lewm, Strathorncat, and Raul, there is a chap in England who developed a replacement power supply/regulator unit for the SP-10s. Check his site (I'm not a customer and have only read his posts on VinylEngine).

And lastly, for Raul and others with interest of moving all electronics away from the motor unit itself, here is a little info on such a project. Sorry that the translation to English is very rough. Such a project is way beyond my basic soldering skills but one can dream.
