Ok with no outputs in the amp it powers up and idles fine...

The amp will produce + - 70 volts of rail and + - 17 regulated volts..


As soon as i put the outputs in the amp ( SSP45N20A'S ) The amp will go into protection mode..


Do i need to order another batch of theese since some amps do not like the new outputs even tho they are the same part number or do i need to go back thru the amp again ??
