Description: Up for sale here is this brand new bare board to build an SMD replacement for the PA3004 IC chip. This chip frequently goes bad in vintage Pioneers such as the SX-780, SX-880, SX-980, SX-1280, and the SA-7700. The chip has been discontinued for decades, and is impossible to find, but luckily some fine folks on Audiokarma designed a replacement for it. This board will let you build that replacement! This is a little circuit board that was designed as a drop-in replacement for the PA3004. It will get your equipment working again. This is larger than the original chip--the board measures 27.3mm x 24.6mm. Still, it should fit just fine in most instances, and will fit nicely in the SX-780 where the larger through-hole version is a little too big. Assembly and installation is fairly easy if you're used to working with SMD stuff. Otherwise it will be a challenge. Installation is fairly simple, you just desolder the chip and install the board in its place. In order to build this board, you will need the following parts (all not included): Mouser Part Number Quantity963-TMK107BBJ475MA-T1 (C1)821-TS4148RYG 4 (D1-D4)755-YFZVFHTR7.5B 1 (D5)863-BC847ALT1G 6 (Q1/2/4/5/6/9)621-FMMT491QTA 1 (Q8)863-BC856ALT1G 2 (Q3/7)667-ERJ-S03J104V 6 (R1-6)667-ERJ-3GEYJ753V 1 (R7)667-ERJ-3GEYJ101V 1 (R8)667-ERJ-S03J154V 1 (R9)667-ERJ-3GEYJ132V 1 (R10)538-22-12-2081 1 (molex connector) The board is marked for easy assembly.
