Is anything known about the disposition of the
obsoleted recording equipment? Did it find use anywhere else?
Were the new cutters installed on existing
lathes, or did they also have to update them too? I'd think that record
companies wanting to addrss the ET market would have to update to new dual speed
lathes (or were there retorfits?) Did vendor companies make the acoustic
cutters, or were they home-brewed at each record company? At what point
did the record companies start to selectively combine microphones and cutters
from different vendors? I assume that the early deals with Western
Electric mandated the use of their microphones in the recording
systems. I also assume that when Scully started to deliver their
feedback cutters circa 1938, that RCA was the mike manufacturer of choice for
state of the art recordings here in the US.
