If the P250 is anything like earlier Perreaux designs, the only fuses are located on the back panel. While i don't know if Peter Perreaux actually designed this unit or not, i know that he is not a "fan" of fuses or any type of protection circuitry due to the sonic degradation that takes place when such devices are used. As such, you might have a fuse for the mains and fuses for the rails on each channel. After that, you are relying on sheer "overdesign" to keep things from popping. A mishap such as shorting the speaker cables even momentarily can be quite costly though. Sean
