Additional information
Drive System and Motor
Hysteresis synchronous motor (115V AC, 60Hz) for speed stability, immune to power fluctuations.
Idler-wheel drive with a precision-ground neoprene tire for consistent torque and minimal wow/flutter.
Speed selection: 33⅓ and 78 RPM (factory default), with an optional 45 RPM idler adapter available.
Platter and Bearing
16" cast aluminum platter, lathe-turned for dynamic balance, with strobe markings for speed verification.
Single-ball thrust bearing for low-friction rotation.
Performance Metrics
Wow and flutter: Meets broadcast standards (exact % unspecified but comparable to 0.1% in similar models like B-12H).
Noise level: Rated 40 dB below average recording level (NARTB standard).
Construction
Chassis: Heavy-duty cast aluminum deck plate (20" W × 16" D) for flush mounting in broadcast consoles.
Weight: 25.8 lbs (11.7 kg), with a reinforced base for vibration isolation.
Tonearm Compatibility
Designed for broadcast tonearms (e.g., Gray Research 106/108), though original arm specifications are unconfirmed.
Supports dual-arm configurations for transcription work (observed in user restorations).
Context
Positioned as an economy version of the B-16H, retaining professional-grade components at a lower cost.
The G-2 Standard variant substitutes a 4-pole induction motor (fixed-speed) and lacks the Deluxe’s hysteresis motor refinement.
