Description: Up for sale here is this brand new bare board to build a replacement for the PA1002A IC chip. This chip frequently goes bad in vintage receivers and tuners such as the Pioneer SX-980, SX-1080, and SX-1280, and can cause you to lose one or both channels of FM. 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 PA1002A. It will get your receiver or tuner working again. The only drawback is that you will lose the FM muting option, so you will hear static between stations no matter whether you have the FM muting on or off. However, it will get your tuner working otherwise. Assembly and installation is fairly easy--you will need a soldering iron, Philips screwdriver, solder, and some sort of desoldering device. I would STRONGLY recommend you replace all the electrolytic and tantalum capacitors on the board that has the PA1002A, or at least replace the ones that are surrounding the PA1002A. These chips often go bad due to shorted capacitors, so you need to replace the bad caps so the new replacement doesn't have issues. Installation is fairly simple, you just desolder the chip and install the board in its place. The board has pins 1&16 marked at one end and 8&9 marked at the other. On the PA1002A chip, pins 1&16 are at the left end and 8&9 are at the right end. You can use your service manual (available at Hifiengine) to figure out the pin locations as well. The pins on the board are slightly fatter than the PA1002A chip's pins, so you will need to push and wiggle it a little, but it will go in fine. The board is slightly larger than the chip, so you may need to adjust the capacitors that surround it, but it's really not difficult. You can see what this looks like when it's installed in the SX-980--that's the last picture. If you have a channel out on FM only, and have a piece of gear that uses a PA1002A, it's fairly likely that the cause is this chip, but it's not guaranteed. I can't help you troubleshoot your tuner, but I would recommend recapping the tuner first and then going from there. In order to build this board, you will need the following parts (all not included): 2x TLE2426CLP transistor1x OPA2134PA IC 1x 110-41-308-41-001000 socket1x RDER71E104K0S1H03A capacitor2x 22-28-4080 wire header The board is marked for easy assembly. If you want to see what it looks like fully assembled, or just want to buy one that's already assembled, I have that available here. If you want to buy the bare board plus all necessary parts in order to assemble it yourself, I have a kit here. 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. Looking for more parts? I have power switches, feet, pushbuttons, top case screws, bottom screws, faceplate screws, white LED fuse lamps, blue LED fuse lamps, 6.3v bi-pin bulbs, 8v bi-pin bulbs, 12v bi-pin bulbs, wired 8v 60ma bulbs, new power cords, new main capacitors for the Marantz 1060/2230, wired Pioneer speaker plug replacements, new 630v yellow film capacitors at 13 different values, a large variety of transistors for vintage stereo repair, and more. Just use "add to cart" on everything you want and then check out for combined shipping.
