The board is in great condition, but it is untested, so what you see you will get it. Shiny and clean like it is right now from the factory.
It has genuine very rare transistors hard to find today (such as Toshiba 2SA818/2SC1628 Toshiba and so on…).
If you already have Sansui Amplifier AU9900A or AU11000A, this very important board is the last chance to get one as spare driver board.
