I've had problems the last couple of weeks with my IC756 Pro III
shutting down in the middle of transmitting.  This weekend I traced it
to the fuses (which were getting warm to the touch).  I  notice that
my SS-30 power supply reports ~ 20 amps being drawn on transmit, and
the fuses are rated at 20 amps.

**  Is 20 amp draw during full-power transmit normal?

**  Are the fuses supposed to be 20A?

**  Should I replace with 25A fuses, or 20A slow-blow, or is there a
bigger problem here?

Thanks & 73 - Jim AD1C
