Additional information
Drive System and Motor
Idler-wheel drive with a neoprene-tired idler for torque transmission, ensuring consistent speed stability.
4-pole induction motor (115V AC, 60Hz) with automatic disengagement in "Off" positions to prevent idler wear.
Platter and Bearing
12" cast aluminum platter, dynamically balanced with a cork-neoprene mat for reduced resonance.
Single-ball thrust bearing for low-friction rotation, typical of Rek-O-Kut’s professional designs.
Performance Metrics
Noise level: 40 dB below average recording level (per NARTB standards).
Wow and flutter: Approximately 0.2% peak (based on 1953 NARTB testing).
Speeds: 33⅓ and 45 RPM (fixed, non-adjustable).
Tonearm and Playback
Proprietary tonearm (likely Rek-O-Kut’s standard S-arm) with compatibility for vintage magnetic or crystal cartridges.
Retractable 45 RPM adapter integrated into the platter hub.
Construction and Dimensions
Chassis: 12" × 15" aluminum deck plate, designed for flush mounting in consoles.
Height: 1⅜" above deck, 5" below deck.
Weight: ~15 lbs (estimated).
Context
Part of Rek-O-Kut’s Rondine series, positioned below the Deluxe models (e.g., B-12H) with fewer speed options.
Targeted at home users and institutions needing reliable playback without variable-speed complexity.
