Replacement for STK465 audio amplifier hybrid IC
The SANYO STK465 hybrid IC in an old Sony audio amplifier TA-AX310 had failed. Several attempts to replace it failed. What is available these days are clones of substandard quality (at least those that I got were). A first attempt to use the LM1876 on a perf-board worked but picked-up unacceptable hum. In designing this replacement PCB, connections were much shorter and shielded by ground plane, eliminating the hum. There is a YouTube video about this here: https://youtu.be/NXuP5z_h9Mw
