Sansui AU-9900 Vintage Stereo Integrated Amplifier Repair And Restoration. Fixing Old Audio - Part
This is the second video showing the repair and restoration of a Sansui AU-9900 integrated amplifier that was produced from 1975-1977. It has the reputation of being one of the finest sounding vintage integrated amplifiers ever produced. In Part Two details of the disassembly and electrolytic capacitor replacements on the driver Assembly(F-2580), and the power transistor/heatsink assembly(F-2581) are shown. In addition I show you how to install new thermal grease and power transistor insulators so the original Sanken power transistors can dissipate heat more efficiently.

Every piece of equipment that you see in my video's is mine. I don't repair other people's equipment and then send them back to their owners. I repair, restore, and bench test every unit. I then install each unit into my own stereo system and do what they were meant to do. Play Music!
