amplifier is TDA7375, data sheet
here
22KuF 25V is temporarily removed due to its bulky size...
FRONT:
REAR
before
after
traces that came off were probably contacted back... bad trace 1 was a tad too serious... so I used wire... all points were checked & shown connected though.... the bad trace on opamp actually caused me to spend quite some time on it... do opamp spoil easily due to overheating?... after a soldering move I blow on it to cool it down... though....
stock opamps: (legs aren't in good shape now...)
