Semi-Automatic
Turntable
The Scott PS-18 is a
belt-driven two-speeds semi-automatic record player complete with factory
installed pickup. Overall performance and soun quality is about average for the
price, though the system is sensitive to external shock and vibration. The motor
starts when the tonearm is moved off its rest. At the end of play the tonearm
recycles to the rest and the motor turns off. The tonearm has a micro-adjust
counterweight that serves as an 0 - 4 gram VTF (vertical Tracking Force)
adjustment calibrated in 0,5 gram increments. There is a calibrated anti-skate.
The pickup rated for 1,5 to 3 grams VTF, is factory installed in a fixed
headshell. The stylus overhang gauge is a reference mark on the shell which
isn't sufficiently accurate for user-installed pickups. The tonearm rest has a
positivie user-applied lock that prevents accidental displacement of the
tonearm from its rest, which might result in stylus damage. The PS-18 we tested
was from the first production run at the factory. Subsequent units are to be
delivered with a universal headshell mount to give the user more flexibility in
cartridge selection and easier installation.
