A friend asked me to look after this TT. It only started to turn on 33 after being pushstarted, but 45 worked fine. After checking the Service Manual (found on Vinyl Engine), I decideded to replace the C 01 Electrolytic Capacitor. That did the trick and the deck worked fine after re- adjusting both speeds with the internal pots.
This is a nice deck from the late '70s that outraces each new Denon 250,- $ or similar plastic deck. Stable and reliable DD Motor even if the electronics need some maintenance after35 years. Good midclass tonearm with SME mount, so it is easy to change and upgrade headshells and cartridges. Nice feature is the holder in the left-back for a spare headshell. I would recommend this deck as a possible bargain if you find a runner- otherwise you should be prepared to replace dryed-out capacitors.
Have fun, Stefan
