For the Sansui AU-666, I hope this can help somebody in the future!!!!
Driver PCBs and the UFO transistor was a bit of a rabbit hole for me. Also will cover the F-1159 Driver PCB's
As an FWI, PAY ATTENTION TO DRIVER BOARD ORIENTATION UNLIKE I DID, THE SECOND YOU INSTALL THEM BACKWARDS and power on, ITS GAME OVER FOR THE 8002 TRANSISTORS ON THE F-1159 board. And you will loose all bias to the power transistors.
List below!!
Q801 , Q803, AMP DIF. is, xa495 or 2sa640 = BC560,
2SA970,
2SA1137
Continue
Q805 and Q897, =CDC8002, = BC639, AND 2SA1358.
BIAS =2SC281 = BC548,
2SC1740 and 2SC1815. ""AnologueBen Mentioned this one""
Drivers, Q811 and Q813 are 2sd708 and 2sa537 =
2SA1708, 2SC4488
2SB647A, 2SD667A
2SB549, 2SD415,
2N5679, 2N5681
Power transistor
Tr815 and the 817 are
2sd188 and 2sa627 =
2SB531, 2SD371.
2SA1072, 2SC 2522.
2SA679, 2SC 1079.
2SA680, 2SC 1080.
2SA747, 2SC 1116.
2S747A, 2SC1116A.
2SA746, 2SC 1115.
