I will include surprisingly well-written instructions, but this is a fairly complicated and delicate rebuild, and you should know what you're doing and have a decent soldering iron and a dim-bulb tester. This kit may not fix your Sansui if it has other issues, but it will definitely help it run better, and should fix almost any driver board problems. Please see my pictures for details.
