Hi,
Apparently mine is far past due for failure. But it is okay because I have several 386s in the drawer. On the other had I may have one of the chips that was *not* an imposter. Those were mentioned by HF Signals. I have eluded the bogey man numerous times over the years. Been to war. Went to sea. Served the local fire dept for a long time. An audio amp that can't take the standard voltage and needs replacement seems kind of trivial.

In v5 and v6? only lm386 has been used.
Even in ver 3? the component failed only because of plugging? mono external speaker pin into stereo socket.
Secondly it failed due to higher voltages lije 13.8 or more? appled to rig.

Hi,
Has anyone tried to connect LM386 instead of the stock audio chip.
If I may request for the schematic.
Thanks
