Somewhat OT...I have an Akai turntable (low end ~$50 in 1982) w/low capacitance tone arm wiring, a Shure V 15 Type 3 w/MR stylus and a Technics SH-400 CD-4 demod, I set the stylus overhang w/free protractor.
CD-4 works well, no sandpaper sound, some momentary distortion on the later (~1976) CD-4 discs due to the Shure cartridge missing most of the upper sideband of the FM carriers.
I recommend getting a Technics SH-400, I adjusted the front/back separation by ear (never had a CD-4 alignment record).
