Differences between Technics SP10 and SP25?

Tube540, those tt's are quite different from each other, though technical parameters have very little to do with that. In my opinion (and I tried all of them) the main issue is weight, and this can be easily changed using DIY plinth. Also, considering that all these models are out of production for many years now it is important to understand where they are coming from. I doubt you want to buy a table that has been working 24/7/365 for the past 10 years or more.

There was an SP-10 Mk II that recently traded cheaply on ebay, that reportedly worked except for a failed external power supply. Anybody know if its external PS is a repairable or replaceable item?

Dear Dgarretson: Replaceable item if you find another second hand and repairable for any good technician even you could find the service manual here: www.vinylengine.com

Dave, Of all things, the external supply of the SP10 MkII is likely to be most repairable. The only possible problem I can think of is that some of the ss devices used therein may be no longer in production, but in most cases there should be modern available devices that can do the same job. Otherwise, it's just a bunch of caps, resistors, etc. Most folks are empirically replacing the electrolytic caps in the PS, just because they are inevitably more than 20 years old, if no previous repair has been done. However, if the motor is kaput, then the table is kaput.

Dear John: Here is some info that confirm what I posted about specs value differences on the same model, take the Denon-DP 80 on Vinylengine and if you go here: http://www.vinylengine.com/library/denon/dp-80.shtml

you can read that the Rumble is -77db but ( same vinylengine ) if you go here: http://www.vinylengine.com/library/denon/direct-drive-turntables.shtml

then you can read -80db on the same spec.
