Bang & Olufsen Beocord 606 Overview
The Beocord 606 is a mid-1960s half-track stereo reel-to-reel tape recorder from B&O's early stereo era, emphasizing sleek Scandinavian design alongside respectable domestic hi-fi performance for speech, music recording, and playback.​

Transport and Format

• Reels: Standard consumer sizes up to 7-inch.​

Performance Specifications

• Frequency response: Approximately 40–50 Hz to 12–15 kHz (±3 dB) at standard speed, reflecting era-appropriate tape and head technology.

• Wow and flutter: Around 0.15–0.20% WRMS, typical for B&O consumer decks.

Audiophile Notes

Positioned between portable Belcantos and pro-grade Beocord 900/1000 models, the 606 prioritizes elegant form with functional stereo capability; valued today for warm tube/solid-state hybrid sound and pristine cosmetics, though rubber parts require restoration for reliable operation.
