Troubleshooting Amp.

[MrQuA4ttro]

So I have isolated my problems to my amplifier---12VDC input, but no output on any of the channels. All fuses are good. I have an Eclipse EA4000.

I am beginning to wonder if my problem lies @ the internal power supply? Its the only thing that I can think of that would be common for all 4 channels. Would anyone know where I can purchase another power supply for this amp??

Any other troubleshooting ideas???

Thank You in Advance
