SP10 Mk II vs Mk III

A couple of guys here were planning to do listening comparisons of the Technics SP10 Mk II vs the Mk III, in their own homes and systems. Has anyone actually completed such a comparison? I am wondering whether the "upgrade" to the Mk III is actually worth it in terms of audible differences between the two tables. Possibly mounting either table in a well done wooden or slate plinth mitigates any sonic differences that would otherwise be heard. I am thinking of Albert Porter and Mike Lavigne in particular, who were going to do the comparison. Thanks for any response.

Lewm, I am sure I can make a copy of my SP-10 mkII service manual. I got it with the machine in the box.

Sorry, Lonestar, I thought you needed a copy yourself. I have one already that I bought from Soundfountain. (So it is not in e-format, only a hard copy. Soundfountain sends hard copies from Germany.) Thank you for your kind offer, however.

There are indeed lots of 1uf 50V (same as "WV") electrolytics on the boards. Remember, this is 70's technology.

SP-10MkII and III service manuals are available for download on vinylengine.com.

Re: number of electrolytic caps

The Service Manual for my SP-10 Mk2A identifies 24 'lytics in the main unit section and 8 in the power unit section. So, not much difference from Peter's count except he didn't include the power section which I've been told is most critical for 'lytic replacement. Of course the 2A replaced the multiple boards of the 2 with a single main board so removal should be easier.

Also, all caps are identified by a V, no WV or W.

Now, since I know so little about electronics, is there a consideration for replacing any of the diodes with new (faster) parts?
