Technics SP 10 mc II. Worth looking at?

The unit can appear to operate properly for some time after its electrolytic capacitors have started leaking, until it doesn’t. When it doesn’t operate properly, there is a high likelihood that other parts that are more difficult to source and more expensive have failed due to the failing electrolytics. It is very inexpensive to replace the electrolytic capacitors a priori. I’ve done it for two different samples of the mk2, myself. For some reason Chakster always disagrees with me on this issue. But you have my own opinion based on experience, and you have his based on his experience. Take your pick.

Was this a display unit, or for some other reason was it in storage for a long period time? If either statement is true, this is a good reason to replace all electrolytic capacitors or at least have a competent person evaluate their condition (which might cost more than empirically replacing them). Total cost in parts is very low. If you have evidence of an overhaul in the last 10-20 years, the lytics are probably ok.

Most SP10s will accept 120V. Those that do not will require 100V. That problem is solved in the USA by using a 120 to 100V step down transformer. Available cheap on eBay.

You are correct that the chip is not used in the SP 10 mk 2. However it is used in some other Technics direct drive turntables, other than the mk 3. In any case I made an error. Thank you for correction. But this is also an indication that the mk 2 is fairly bulletproof as far as irreplaceable parts.

The only "irreplaceable" part is the single IC, MN6042.  JP Jones has developed a replacement part for the MN6042, built from discrete SMD components.  So there is nothing to fear in terms of parts.  His business is called "Fidelis Analog", and you can find it on-line.  If you are buying an aged device, andt you want it to work precisely up to its original specification, it just makes sense to replace all the electrolytic capacitors, unless you can verify that it was recently done by a previous owner.  The OEM capacitors would now be at least 40 years old.  However, there is no need to be concerned about film capacitors; they last "forever" unless their voltage rating has been exceeded in circuit.  In connection with replacing the electrolytics, you can think about having it calibrated as well.  These precautionary service steps should not be expensive.  In the US, one can buy all the needed capacitors for under $20.  If you needed to replace the MN6042 IC, that would cost more; consult JP.  If the tt runs up to speed and is speed stable, chances are you do not need a new IC.
