What should I price a Thorens TD-224 turntable?

You should check hifishark.com.

This is a very rare and complex turntable. The price will vary depending on how well and whether it works properly. Also whether it has been serviced recently by a competent and qualified technician.

That is a super rare deck in decent to good condition it should fetch quite a lot!

I hope so! Thank you jond!
