Hello. I’m new on forum. I have blown amplifier digipro 1000 from DB technologies. I found some bad parts, but cannot identify this diode. It has marking 31. In wiring it is d12 and d13. Scheme is there: https://elektrotanya.com/cgi-bin/download2.cgi?uid=19628&cid=1541665480&fid=289613&file=db-technologies_s10_sch_pcb.pdf&x=28&y=15
Thank you in advance.
Hi to all,
I am looking many days for schematics for the LAX MA7200 audio amplifier.
I think it is made in far east and is copy of other model, probably a QSE brand.
Similar to this-or made from the same factory-is the ODY-PRO 7200, which has a board with a printed label "XILICA" which is a Canadian company.
Any of the schematics is great help for me, as I have to service more than 20 units.
In case you met any of them please inform.
Thanks for your time for reading
I already replaced the TDA 2030A audio output transistor and the sound returned but it is very noisy I didn't find any other faulty components, I suspect it's the speaker that burned out. The problem is that I don't have another speaker to test here
Sziasztok!
Kenwood, KDC-W7041U típusú autórádió kódját sajnos elfelejtettük.
Kérem a segítségeteket!
