This is part 2 and the conclusion of the amplifier repair. Part 1 can be found here: • 187 - Repair of a Sony TA-AX310 Integrated...
In part 2, I discuss the design constraints to implement an alternative solution that doesn't rely on finding working clones of the long obsolete Sanyo STK465 Hybrid IC. In the end I designed a replacement PCB for my solution. This design is available in PCBWay's Shared Project library here: https://www.pcbway.com/project/sharep...
Note that for the month of September 2025 PCBWay offers free purple solder masks for free.
