However, keep in mind that 78's are a shellac-based compound, whilr 33's
and 45's are vinyl. The main disadvantage of vinyl is that it can be
incoorectibly warped by high temperatures, while shellac discs need
only be rewarmed to flexibility and bent back to flat!
The question would be whether it is possible to find a less-grainy
"filler" for the compund, since that is what causes the surface noise...
