[TenTec] Omni VI Power Cable Fuse??

[Steve]

My Omni VI came with a DC power cable that has fuses in both the + and -
leads.  They are 10 amp fast blow fuses.  I have already blown 2 of these
when running at rated output power.  It seems to me that these fuse's are a
bit light.  Are these the correct value?  I thought I needed a power supply
that can deliver 20 amps at 12 volts to run the radio correctly.

Should I change these to slo-blo fuses or just get 20 amp fast acting
fuses??
