This NG is called rec.audio.car. Your picture is of a home amplifier. Not
even close to the same environment. Car=harsh environment. Home=not harsh
environment. There is lots of good old home equipment available, I find and
sometimes buy it at the local good will stores. I have owned Sony and
Pioneer amps way back in the late 70's, but fish paper PCB's do not hold up
all that well in the long term. They all gave out and the cost to diagnose
and repair was prohibitive.
