Description: Up for sale here is this brand new Made in USA replacement for the BA312 IC chip. This chip frequently goes bad in vintage receivers such as the Sansui 9090DB, Sansui 881, and Marantz 2275, and can cause you to have weak or distorted sound. The chip has been discontinued for decades, and is difficult to find, but luckily some fine folks on Audiokarma designed a replacement for it. This listing is for a completely built BA312 replacement, so all you have to do is install it. While some boards are built with tiny SMD parts that don't have the correct vintage look, this board uses through-hole parts that are normal-sized. The board measures 19.4mm x 15.3mm and is 10mm thick, including the components and solder joints. Installation is fairly easy--you will need a soldering iron, solder, and some sort of desoldering device. I would recommend a fairly fine-point soldering iron (and thin solder), as a wider "chisel tip" will make installing this difficult. I used a Hakko iron with a 1mm tip and it worked well. I would STRONGLY recommend you replace all the electrolytic and tantalum capacitors on the board that has the BA312, or at least replace the ones that are surrounding the BA312. These chips sometimes go bad due to shorted or leaky capacitors, so you need to replace the bad caps so the new replacement doesn't have issues. If you want to save a lot of money, you can buy the bare board and components to build your own BA312 replacement right here. If you want to buy a genuine NOS unused BA312 chip, I have that available 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.
