Tonight I started merrily playing 2-minute Gold Moldies, and after about the sixth one, it really started to sound crappy - more surface noise than music (Collins & Harlan - "A-float on a five dollar note" ). I stopped the machine, and removed the sound box, figuring the stylus might be loaded-up with crud.
To my horror, I discovered that I'd been playing all these 2-minute cylinders on a 4-minute H reproducer (repro).
So, how much damage might this have caused the records or reproducer ?
All of these cylinders have some mold damage, so no "mint" records were victimized....
( Boy do I feel like a chump ! )
