Darn I'd be inclined to run at least a 40amp supply. Does the paperwork tell you how much current the thing draws?? |

I'm with Ozzie's suggestion. At least a minumum of 40amp power supply. If you are trying to run the radio on it also? then add up your total amperage including the radio. It''s cheaper in the long run. |

agree just a quick rule figure at least 10 amps per 100 watts Myself i have a 25 amp supply it runs my ham station just fine. |

A 30 amp should just get you buy. I'm with Ozzie and Ca346. Go with a 40 amp! The bigger the supply, the easier the work load on the amp.

Oh 40 amps for sure,minimum,at 438 watts mine only drops to 12.5 volts,but it will drop to ten if I eat the mike and cause splatter,splatter will over work your power supply 'course if you got a 70 you could seriously blow smoke,and do things you wouldn't normaly do with that amp.BUT the biggest help I did for my rig was run a dedicated line from the panel to the P.S.,20 amp breaker,12 gage wire,absolutely knocked out rf getting into my house wiring,see I got a mobile home,panel on the pole is where I went and used buryable line,poked a hole in the wall,you can do this as a homeowner in micigan,don't have to follow code to the letter AND my system is safe.Bigbob |
