Dual 1009 : Is it a good TT to buy ?

My first "stereo system" purchased in 1966 included a Dual 1009, along with Dynaco electronics and AR speakers.

I don't know much about Duals but there were many models that followed that I assume were better. Typical recommendations for the older Duals are for the 12xx series. I've never seen anyone recommend a 1009.

Considering mechanical complexity, an old Dual and a Rega could not be much further apart!

Basically it means I should chuck it ?

You are prolly better off with the Rega.
If you can find a used VPI Scout in good shape and have a decent cartridge I imagine you would like it very very much. The investment in the Cart and don't forget the Phono stage may be more than you want to spend. OTOH a Scout is easy to sell.

Buy the Rega and put a Grado on it if your objective is to buy once and be happy for a long time. I sold every moving magnet made a number of years ago (Before Benz Micro was in market) Grado was then the best MM, followed by Goldring. The Dual is not a good TT and will degrade your sound. Its only virtue was that it was a step up from the Pioneers and Technics made in the 70's and 80's. Shure cartidges while they track well have a dry antiseptic sound whereas the Grado's have great base and excellent mid range tonal color.
