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.

Schematic is available either from Vinyl Engine or from a pay site. (I can't remember where I got it.) If you're knowledgable, you may be able to read it yourself. I build tube stuff all the time, but I cannot make out what's going on in the SP10 schematic.
Does any one know of a good tech who can change out the capacitors since I wouldn't know a capacitor from a diode? Also, does anyone know of a tech comfortable with cleaning out and replacing the old bearing oil?
The SP10 MkII power supply has three voltages +5V, +32.5V and +140V. The 140V supply is used to power the strobe light. It is simple half wave rectifier circuit using a single diode, protected by a 315mA fuse - always check fuse F3 before anything else.
Microstrip.

The two voltages responsible for operation, +5 volt and +32.5 volt are the only important ones. The strobe is not necessary and most people agree it only adds noise.

I wonder if it would improve performance of MK2 if a tube circuit were designed to replace the stock Technics supply?
Kmccarty, I know of such a tech, in the Washington DC/northern VA area. He is highly skilled and of very high integrity. Consequently, he has a backlog of work for 6-8 weeks at all times. (He's got my Mk II now and previously did my Denon DP80.) If you want more info, please contact me via e-mail.

Albert, Assuming I ever could find a Mk III, does it too have an oiled bearing, and does it require a shipping bracket for transport?
