Just dug out a 20 year old Technics SL-BD27 turntable. This thing has seldom, if ever been played, but I thought this might be a good starter to get into vinyl. Well, I hook it up and got not sound. I replace the needle and now I get sound if I turn the volume waay up on my AVR. What is a likely cause of this? Should I try to replace the cartridge or maybe just forget about it and find another turntable (or more likely continue on without a turntable)?
