Hi
I found a Kenwood KA 6000 HiFi amplifier.
When i power it on the small indicator lights are on, but no sound at all.
It has three replaceable fuses on the back of the cabinet. two 5A and one
that has this text "4A (6x30) SCHURTER". These are all intact. I had a look
inside and found 2A fuse that was intact and then a burned F5A fuse soldered
between a red wire coming out of a large black box that i guess i a
tranformer(?). This box is 11½ by 9½ by 9½ cm and on it is written 01-191W
(not sure it the last digit 01-19_W). At one side there is coming two red
wires, a blue a black. At the other side it has a white, a black a yellow
and a red coming out. the white one is going to the 4A fuse on the back of
the cabinet.
At the other end the burned F5A fuse is connected to a point where three
capacitors are connected. Or at least one 0.022 capacitor and two things i
newer saw before which i GUESS are capacitors. On the one where i can read
the text is written "SA-2Z 041". They have the shape of a hat and are made
out of metal.
I replaced this fuse, but when i turned on the power there was a short
buzz/hum and then nothing. I looked at the fuse was burned again.
Generally the insides look very clean and healthy. I se no liquids, sings of
smoke/burning or the like. Yet i didnt discover any loose wires og short
circuits.
Any ideas where to look now?
I can describe some more if that helps.
Thanks in advance
