sure 2x100w problem

[LandIsland]

Hi

Building an amplifier with the sure 2x100w board and a 24V power supply from sure as well. Tested it when I recieved it and it worked well. But after some modification it won't work. It recieves power, both the fan and the power LED works, but no sound from the speakers. Measured the output to 0.002V wich seems way to low(not that good at electronics). The things i modified is just removal of onboard RCA-sockets and DC-socket. Not touched anything other than that. Read in another thread that R20 could be the problem, but I think that would be strange since it has worked before..

First, reassemble it back exactly the way it was before, and see if it works.

Phew, controlled the speaker wich is just a testing speaker and it occured that one of the wires was not properly connected. Wich means the amplifier is working perfectly!!
