I've got a neat old portable phonograph (the wind-up kind) that I just love, but it only plays shellac 78's from the first half of the century, and I was wondering if I made a few tweaks, would I be able to play a 33 or 45? Now don't get me wrong, I know the difference between the new and old records, if I plop down a vinyl record on there and play it with a steel needle, I'll shred it to ribbons, though I had an idea: I've heard it's possible to slow down the turntable with the break to about 45-33 rpm and if I were to finagle some kind of new needle from a cartridge in the sound box while simultaneously taking some weight off the tonearm (maybe by suspending it with a string?) would that be just crazy enough to work? Or do vinyl records absolutely require electronic amplification? Would the sound be too quiet? What do you think? If I COULD get it to work, it would be totally awesome... Has anyone tried this before? Suggestions would be greatly appreciated! Also I didn't really know which category to post this in...
