Posted by SignOfZeta on January 21, 2023 at 10:57:05 EST in reply to I found a bunch of home recording acetate discs at a thrift store once and was disappointed to find that they were mostly blanks. I can confirm that these had indeed been manufactured before 1976. (n/t) from Loopy and Opa Opa.
Do you know what kind of machine was used to record on them? Were they 12”? The only acetate discs I’ve seen were cut on normal record lathes. There was at least one f0rm of aluminum transcr1ption discs used in the Lomax days where the mechanicals weren’t too huge but still professionally priced for sure.
