I Have a Sansui AU-717 Amp
the left channels on the speaker out are not working on Speaker A & Speaker B
I also have a Lexicon NT-312 Amp
that does not come on anymore
I replace the glass fuses and no help
the power light does not come on but the clipping light will come on to a steady green light
wanted to know if there is any repair shops or someone that can fix it?
I am in the southern cali area.
