The power supply fets failed in this amp The driver for the fets also failed..
It is a 6 pin suface mount transistor Board Location Q7 which the Schematic says the part number is C2045E5 I cant find that anywhere..
Does anyone know what the part number is for the driver or what i can use??

I called in a favor lets see what they find for you. As soon as I find out I will let you know either way if they have it or not.

This is what you are looking for?
I did not find this but a friend was able to locate it and provide me with the information.

Sorry to raise a dead thread!!
Hey, was wondering where you found this diagram, do you happen to have anything for the rest of the amplifier

Yes actually....It powers up, and then proceeds to slowly flash the protect button, none of the large transistors seem to be damaged though...
I'm sorry that I lift an old topic , but I need a circuit of this amplifier . Please send it to my email vados_555@mail.ru You are my last hope!
I too can't figure out this ampifier. It draws current with just b+ and ground. I'm thinking diodes failed in numous places as all of the main transistors are not shorted not open. All resistors seem to be in tolerence. Any help anyone can give me I would greatly appreciate it.
Does anyone have the part number for the multiplex control unit? Atmega (0952 tiny13v 10su) imprint.?
I'm sorry but this is a flyback power supply amp. It probably won't work to have only remote and ground connected. I've never tried it on one of these.
Why do you think the logic components have failed?

I get like an intermediate power up where I can see drive and then just off. I can't seem to figure it out. It draws current then normal to off. I kind of haft to remove power then power a few times and it has a show of life and I can see a drive wave start to build then as the rail voltage increases it just shuts off.
Now all of the sudden perry it's powered up and working? Something is failing??? It's worked twice now...
If you can, take voltage readings on the PS driver IC and MCU to see what's different when working and not working.
