I am the owner of a second hand TD125 (Mk1) with an SME 3009 arm and Shure V15 cartridge that I picked up about 25 years ago. It has languished, unloved, and wrapped up brown paper in the garage ever since. (Don't flame me!)
It came from a radio station where I worked for a while as a tech. It was sitting in the equipment storeroom and excess to requirements, so I bought it with a view to getting it going.
The motor doesn't spin up - maybe that's why it was in the radio station storeroom - so checking the electronics will be the first job.
I finally decided that maybe I should finally do just that. If I don't, then I know that when I die, my daughter will toss it in the rubbish with all my other good stuff. She won't know what's good and what's not - and there's a lot of good stuff - electronic test equipment, workshop tools, woodworking machinery, etc!
The turntable needs a plinth as it came without one - I'll hunt around for dimensioned diagrams and will get my trusty table-saw to work.
