Vintage Sansui AU-7700 Integrated Amplifier – Fully Serviced & Recapped
Up for sale is a classic Sansui AU-7700 integrated amplifier, a beautiful piece from the golden age of hi-fi known for its excellent build quality, distinctive Sansui styling, and powerful, detailed sound.
This AU-7700 has received extensive electronic servicing throughout, with the electrolytic capacitors and known problematic transistors addressed across the boards.
Service & Restoration Includes:
• Electrolytic capacitors replaced throughout the amplifier
• High-quality Nichicon, WIMA, and KEMET components used where appropriate
• Known problematic/failure-prone transistors replaced across the boards
• Controls, pots, and switches thoroughly cleaned and serviced
• Main filter capacitors tested and found to be well within tolerance, so the original Sansui filter capacitors were retained
• Fully tested and performing as it should
Rather than replacing components simply for the sake of replacing them, the original main filter capacitors were tested and found to still be performing properly. They were therefore kept in place while the rest of the amplifier received extensive reliability-focused service.
Why This One?
The AU-7700 is a fantastic example of classic Sansui engineering and has become increasingly desirable among vintage audio enthusiasts. You can find unrestored examples, but many are still operating with aging capacitors and known problematic transistors.
This one has already had the important electronic work completed, giving you less risk, improved reliability, and peace of mind while maintaining originality where the original components continue to test properly.
Condition
Very nice vintage condition with great overall presentation. The classic black faceplate and controls show beautifully, everything operates smoothly, and most importantly, this amplifier sounds fantastic.
Fully serviced, tested, and ready for its new owner.
