Technics SP 10 mc II. Worth looking at?

Nice, use it as is, you don’t need to change anything in SP-10 mkII if everything is ok. You could definitely upgrade the tonearm.

Chakster, I have SH-10E with 120v 60hz, 220v 50hz switchable power, only one I've ever seen. I purchased from Australia (I'm in US) where it was used in ABC mobile unit.
Laughingfrog, good for you! I much prefer my SP10 II over the many belt drive tts I used over many years.

I progressed through various motor drive TT's to DD and my impressive TT is the SP10 Mk II that is in use very regularly.
I have no problems with other motor drives on TT's and make time to hear them perform.

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.

Turn on your Technics first, if it’s fine don’t do anything. Caps might be already replaced by a previous user.
