I just picked this up at Goodwill very cheap. I'm a little excited and a little nervous. I am an ametuer at electronics and with my jump in head over heals attitude, I am worried about getting in over my head and have a few questions.
1) This console has 2 turntables and a remote control, the cabinet is in so so shape. Is this anything extremely valuable that I don't want to touch?
2) If not what resources are out there to help me learn what I need to know to get this puppy up and going again?
Any and all input is welcome, I just kinda lucked into this thing and thought it was super cool.









Thank You all for your help!
