Unless you are trying to restore the unit for its own sake (and
and removing it from its cabinet argue against that) and just
want to be able
to reproduce wire recordings, I would suggest getting a
such as the one at
VINTAGE WEBSTER 80-1 PORTABLE WIRE RECORDER
These units often sell for $20 to $40 (though apparently not on
have better and more serviceable mechanisms and also have built
in line level
inputs and outputs.
The combination turntable and wire types depend on the rim-drive
for speed regulation which is never very reliable, even for records.
As for the electronics, if it produces good sound, the capacitors
survived full voltage reforming, but their life span is
questionable. I have
too often seen smoke pouring from equipment of this vintage even
after it has
been in use for many hours without problems. The only safe
approach is to
replace all electrolytic and paper capacitors that are more than
century old. Otherwise do not leave it on unattended and use it
periods at a time only.
