I'm not familiar with the model of TT that you have, but many mass-market designs typical of the era will display problems like wiggly tonearm bearings, motor rumble, platter resonances, bouncy suspensions, and susceptability to coloration, mistracking, noisiness and feedback in general (especially if they're changers). You may want to take it to a TT specialist for an assessment of its condition and potential before starting down a road with it. It would be a shame if your foray back into analog were disappointed by the wrong tool for the job - peoples' audio expectations have been raised a lot since the time some of these "oldies (maybe not goldies)" were made. Who knows, yours may be worth working with, but there were reasons Linn came out with the LP12!
