Hi,
Currently i got one unit of HH Electronic MX1200 power amplifier.it can be turned on without any indicator of protect LED being in ON state.But the problem is, it can't detect any input signal.So, when i open the cover, i noticed that the 1A fuse of both channel keep blown even i had replaced it.Original owner said it the power amp has gone down since he "misshorted" the + and - terminal of the speaker.Any idea? by the way i had attached the schematic for reference.
It uses 10 pair of BUZ901 and BUZ906 Mosfet transistor.total 20 for both channel.
