Hello, greetings to all DIYAUDIO members. I am here asking for some help regarding my amplifier.
I will tell a brief story about what happened.
That day I was busking using the FISHMAN LOUDBOX ARTIST and I noticed that my amp was not working as usual. then I tried to open the body amp and I didn't see anything happening.
so I went to send technician "A" to repair the amp. the technician said "the preamp IC was found to be defective" so I bought it and the model was TAS5603B and the technician installed it. And after a few days, the technician changed the item but my amplifier is still not working. I took it back and changed to another technician.
then I sent it to the other technician "B" and when he opened the preamp IC and found that the board was burnt.
The technician asked me to look for the fishman loudspeaker schematic but couldn't find it. until I found this forum to ask for help from all my friends to get the schematic.
Please help me.
