No sound, Sony str-db930 qs fuses blow?
Hello everyone, such a problem, at one point, I listened to music, not very loudly, once, the amplifier went into protection, turned it off, turned it on, worked for a second and again in defense, then turned it off, turned it on, it turned on but the sound no longer output
Dismantled, found 2 blown fuses (125V 8A) on the DC
board 125v in Russia is not the most popular voltage
Installed, turned on, got burned again
Made a fat bug and connected it through a light bulb, the party started, the light blinked, and the amplifier clicked a relay
Before installing the bug, pulled out all the contents, started looking and poking the tester into something that could burn out , everything was normal, I even thought about the diode bridge, measured it, everything is fine, but still decided to replace it
Another strange moment, on the back of the amplifier, there is a socket
, and so, it squeaks (closed)
if you turn it on through a light bulb without fuses, the lamp barely burns, the amplifier turns on by clicking two relays
. So I wanted to know if anyone knows what the problem might be and tell, otherwise it's very insulting
