Up for sale here is this brand new Sansui F-2624 bare circuit board.  The F-2624 driver board is used in the Sansui 7070, 8080DB, 9090DB, 890DB, 990DB, QRX-8001, and QRX-9001, and sometimes the old boards can be damaged either from use or from repair/rebuild work. 

This is a new replacement board.  It is redesigned slightly to use modern bias transistors rather than the 2SC984 or STV3H.  This is the same dimensions as the old board, and will fit nicely in your receiver.  This is a super-high-quality ENIG-coated circuit board, and is unbelievably nicer than the originals.

This board is designed to use modern transistors, capacitors, and diodes, and is marked (and sized) for them.  The board is marked with part specs so it's easy to install new parts.  I do have a parts list to populate a board--it is at the bottom of this listing.  You will need to build this out yourself--it is obviously not complete, and I do not have complete boards available.  This is fairly advanced-level work.

US shipping and handling is $5, and international is $18, no matter what quantity you buy. All my small parts are set up for combined shipping, so just use the "add to cart" feature and then check out all at once, and it will combine shipping. If you have any questions, please ask.

Just FYI, the 10311048 molex plug (the top one at J3) is currently out of stock from distributors, so I have them available here.  I also have the bottom J1/J2 12-pin molex jacks available here.
