Pioneer brochure featuring two turntables - PL-31E at ¥42,500 and PL-25E at ¥30,000, both belt-driven with S-shaped tonearm and magnetic anti-skating. The PL-31E has a heavier 1.3 kg platter with a hysteresis synchronous motor, while the PL-25E is a kilogram lighter. The back page promotes compatibility with matrix 4-channel playback - a hot topic in 1971.
