Not to happy about this -sound weshost PS.
It says -suitable for high -end PS-its not.This is as "simple" as you can get in electronics.
The input fuse is a surge limiting fuse there fore a s/c in the full-wave rectifier yes the fuse will blow but where is the protection for the AMP !!
the secondary circuit is "straight through" there is nothing stopping total damage to the amp from a fault condition less than the value of the fuse.
A real -Hi-end PS would at least have quality voltage regulators which a capable of acting quicker than a fuse and shutting down in the event of a fault condition.
Therebye saving outright destruction of the amp.
If you dont have the technical knowledge to fit regulators then please at least fit OUTPUT fuses.
