| I realise that this post is over 6 months old, but I got the exact same problem, and I can't find any hint other than this (which isn't really helpful, apart from saying I'm not alone, and that replacing transistors or resistors doesn't seem to be the answer).
So... if Canixys has found a solution, or anybody else has any hint, I'd like to hear it 
Thanks |

| Hi!
I need some help with this amplifier from pioneer. Since I can´t find service manual or repair tip on the net. The problem is that 2 resistors gets really hot, these resistors value is 0,22 Ohm 2-3 watt. I can´t have this thing on more than 5-10 sec beacuse they get very hot and if I have it on longer they will burn. I have change 5 transistor (4 amplifier transistors), and 2 resistors. Hope someone can help me, and if someone have the schematics or service manual I would be happy 
Cheers Canixys |
