Report on "Vinyl-Engine":
SL-5300: Similar in layout to Tech nics SL-3300. The SL-5300 has a quartz control and a slide button to turn off the quartz to adjust the pitch. However, there is only one pitch control for both speeds, no neutral position between speeds 33 and 45. Also has a lamp for illuminating the record and the stylus in low light conditions. The speed accuracy is permanently switched on. SL-5310 is the same, but in black finish.
