Has anyone tested the ACTUAL blow current for fuses eg 5A 10A 30A..

I often do not have fuses at the correct value and FUSE down only to find that I can run them at considerably higher amps than rated eg 30A fuses at 50A and they fail to blow. This is intermittent use say 30% - 50% in psu's used for CW and QRS3 normally in FET AMPS

This is normal fuse wire bought wrapped on card.

It looks like your PA fets could be in trouble under certain circumstances.
