All the more reason for doing it properly.
A clean and possibly a wet playing on a decent turntable.

May we ask what discs these are?

If so, you could take an output from the top and bottom of
the volume control, which would be a better level and less
distorted than the speaker output.
Wherever you take the output from, check you don't have a live
chassis.


Would these need attenuating?

The level at the volume control should be reasonable for a
PC soundcard line-in.
