Bang & Olufsen BeoGram 2404 Turntable (1972)
The Bang & Olufsen BeoGram 2404 was introduced in 1972. It is part of B&O's turntable series from the 1970s. It brought tangential (linear) tracking and a modular cartridge system to a broader audiophile market.

Historical Context
The 2404 came out while B&O was pushing minimalist design and new engineering. Unlike a conventional pivoted tonearm, it used a tangential tracking system. The tonearm moves in a straight line across the record and keeps a 90-degree angle to the groove. That removes the tracking error and distortion built into radial arms.
The 2404 is part of B&O's modular SM system and used plug-in cartridges. Users could swap between moving magnet types (like the SM 5 or SM 7) without tools or realignment. It also had a suspended sub-chassis to isolate vibrations. Discerning listeners and interior designers both liked it.
The construction is low-profile aluminum and acrylic, in the Scandinavian style, and it was often integrated into B&O's BeoVision and BeoCenter systems. Linear tracking had previously been reserved for ultra-high-end models. The 2404 helped bring it to more buyers.
Sound Signature
The BeoGram 2404 has a clean, neutral, and detailed sound, typical of well-implemented tangential tracking systems. With near-zero tracking error, it pulls fine detail from vinyl with minimal distortion, especially in the inner grooves where conventional arms struggle. The low-mass tonearm and precision guide rail give accurate transient response and excellent channel separation.
With a well-maintained SM series cartridge, the 2404 gives a balanced frequency response and a spacious soundstage. It remains competitive even by modern standards, particularly in midrange clarity and imaging precision.
Maintenance and Tips
Because of its age, the BeoGram 2404 needs careful maintenance to perform well:
- Drive Belt: Replace the deteriorated rubber belt (available from specialty vintage audio suppliers). A worn belt causes speed instability and rumble.
- Suspension System: Check the four damping springs in the suspended sub-chassis. Sagging or hardened springs reduce vibration isolation—replacements are available.
- Tonearm Mechanism: Ensure the linear tracking rail is clean and lubricated. Stiff movement or jerky motion indicates dried grease or debris.
- Cartridge Availability: Original B&O SM cartridges are rare. Consider using an adapter (e.g., SM-to-standard headshell) to mount modern MM/MC cartridges for better availability and performance.
- Cleaning: Use isopropyl alcohol and lint-free cloth for the platter and tonearm. Avoid abrasive cleaners on acrylic parts.
- Calibration: Verify tracking force and anti-skate (if applicable) using a digital scale, especially after cartridge changes.
Servicing every few years is recommended to preserve function and value.
Collectibility and Market Value
The BeoGram 2404 has a collectibility rating of 7/10. Buyers prize its design heritage, its engineering, and its place in B&O's audio systems. Units in working condition with original packaging, remote (if applicable), and SM cartridges command higher prices.
- Market Value: $150–$400 USD
- Non-working or heavily worn units: $100–$150
- Fully serviced with original cartridge: $300–$400
Enthusiasts and interior collectors both seek the 2404 for its design and its place in the evolution of high-fidelity turntables.
Conclusion
The Bang & Olufsen BeoGram 2404 is more than a turntable—it’s a statement of design philosophy and engineering excellence. Its pioneering use of linear tracking, modular cartridge system, and elegant construction make it a standout piece from the 1970s audio landscape. With proper care, the 2404 continues to deliver exceptional analog performance, bridging the gap between vintage charm and audiophile precision.
