From original owner Who clearly took very good care of it! Tubes are Scott Amperex and Telefunken. All inputs and outputs tested except for phono inputs. The headphone input and some of the inputs on the back needs to be jiggled around to engage so those need to be thoroughly cleaned. Both input and Stereo selectors need to be cleaned as they crackle when switched. All other pots and switches are dead quiet! The sound on both Stereo and mono is crisp clean and amazing! Metal cabinet ha...s nice Scott logo accents. Comes with original box which will be packed inside a larger box with industrial foam. I have many additional pictures if you need more detailOn Jul-06-19 at 04:42:30 PDT, seller added the following information:Transformer number is TR13-2-1 352152 mullard?
