The Accuphase P-300 is considered a hidden gem in the world of amplifiers for several reasons:

 

• Exceptional build quality: The P-300 is described as being "built like a battleship" and "bulletproof" when properly maintained. This robust construction contributes to its longevity and reliability.
• Impressive sound quality: It delivers powerful and dynamic performance with excellent drive capability for various speaker loads.The amplifier is noted for its clean and detailed sound reproduction.
• Versatility: The P-300 features multiple inputs, including front panel RCA inputs, individual channel volume controls, and a high-quality headphone output, making it highly flexible for various setups.
• Value for money: When compared to newer, more expensive amplifiers, a well-maintained P-300 can offer comparable performance at a fraction of the cost.
• Repairability: Despite its age, the P-300 is highly serviceable, making it a cost-effective option for long-term ownership.
• Classic design: The amplifier features timeless styling with beautiful analog meters, appealing to those who appreciate vintage audio aesthetics.
• Power output: With 150 watts per channel into 8Ω and the ability to produce up to 400 watts of peak power into a 4-ohm load, the P-300 can drive most speaker loads effectively.
• Advanced circuitry: The P-300 employs sophisticated design elements, such as a direct-coupled complementary symmetrical circuit topology and carefully selected components, contributing to its high-quality sound.

 

These factors combine to make the Accuphase P-300 a desirable and often overlooked option for audiophiles seeking high-performance amplification without the premium price tag of newer models.

This Accuphase P-300V (Japan Domestic Model) has been meticulously cleaned and restored, both inside and out, by our Takumi (Master Craftsmen), who carried out a complete overhaul. 

 

This amplifier has been very well looked after by its original Japanese owner. Since its return, it has been put through 3 weeks of testing by us at Vintage Japan HiFi. The results? It sounds as powerful and clear, truly exceptional for a piece of its era.

 

Condition Overview:

• Cosmetic Condition: 8/10 – Excellent overall with very clean front panel, top cover and back plate with very minimal scratches which is rare for this amplifier of this age. 
• Side wooden panel: 6.5/10 - Both wooden panels have more visible scratches which is common signs of age.
• Performance: 9/10 – Operating at peak specifications with amazing sound clarity and depth.

The side wooden panels can be custom made with solid wood of your choice, at an extra cost - contact us to find out more.

 

Note: Our overhaul service focuses on preserving the original sonic character of the amplifier. We only replace non-functioning electronic parts, ensuring each piece remains true to its factory specifications. Unlike the common practice in many US HiFi workshops, where all capacitors, transistors, and other components are replaced, our ex-Sansui engineers and technicians advise against this, as it changes the amplifier’s authentic sound profile. We honour this approach to maintenance and restoration. However, if you’re looking for more extensive "recapping," feel free to reach out by email for a personalized service quote.

For any vintage audio hifi equipment:

Please be aware that, given this vintage hifi equipment's age, certain switches and original parts are no longer in production. While we’ve thoroughly cleaned and lubricated any “gari gari” scratchy controls (as they’re called in Japan), it’s simply not possible to eliminate this characteristic entirely.

We recommend regular servicing every 2 to 3 years, depending on the equipment, to keep this vintage hifi in peak condition. This advice applies to all vintage equipment—be cautious of sellers who claim "brand-new condition" or “better than original.” Minor scratchy sounds in control knobs are typical for vintage gear and should not be seen as a defect but rather a natural sign of its history.

For optimal sound quality, we advise pairing this amplifier with a speakers that match its power efficiency. If you need guidance on amplifier matching, feel free to reach out for assistance.
