If you are looking for a way to restore your vintage Sansui or Marantz HIFI equipment, you might be interested in this project: a new replacement PCB for the Rohm BA312 amplifier IC.
The Rohm BA312 is an old amplifier IC that was widely used in many HIFI applications, but it is now obsolete and hard to find. That’s why I designed this small PCB that can replace the BA312 with modern components. You can either buy it as a DIY kit and customize it to your needs, or as a pre-assembled kit that is ready to use.
