Audiolabyrinth, Unless your turntables have a known history of having been serviced recently, I suggest you may want to replace all the electrolytic capacitors in both, and then have a competent technician calibrate the drive systems. That's the only way you can be sure you are getting the most out of them, although if they operate without noticeable issues, you're probably OK. One thing I've observed is that the market values of mid-level vintage DD's like your two is not much below what you would have to pay for the really top quality ones. For example, you can find Denon DP80s or DP75s for less than a thousand dollars. Another good one is the Kenwood KD550, which seems to be easy to find for around $500. You might also luck out and find a Victor TT101 for under $1000; that would be a great bargain, but they are rare outside of Japan. Yamaha GT2000 is another one to look for. Between one and two thousand $, you can hope to find a Technics SP10 Mk2. I'd actually rank the DP80, TT101, and GT2000 slightly ahead of the SP10 Mk2, certainly its equal. Well, you said you were "collecting"...
