Hello Gentlemen,
My question is on the Boomer 300 Base Amp cover says 25amp. Is this a continous 25amps on the power supply or what? On the 500 it says 35amps, same question. Thanks for your help. I would just like to know before I buy.

My understanding is that it is continous... but please note that if you are going to hook a mobile radio up to the power supply on, some amps will be lost when you r also running the box at the same time, running both could put to much of a strain on so just try to use only one or the other unless u have it hooked up to a base radio then your set.... Experiecne is how i found this out, power supply in mine is now fried from useing both... Good luck.....

Uhh, I'm pretty sure it refers to what you can draw INTERMITTENTLY if you use it JUST as a power supply, with the amplifier itself NOT KEYED. As far as I know, nobody rates power supplies for continuous, unless they use that word, usually in large letters. The industry-standard called ICAS, for Intermittent Communications and Amateur Service calls for a 1-in3 (or 33%, if you will) duty cycle, meaning one minute keyed for every two minutes to cool back down. If you ever see the acronym "CCS" that translates to Continuous Commercial Service. The last place I saw THAT was written on a Peter Dahl transformer spec. sticker.
The "25" and "35" ratings pretty well reflect what the amplifier inside will draw when running hard. I have a simple rule for running a radio from the amplifier power terminals: Turn the drive down until the meter light on the radio stops blinking in a serious way. It's a sneaky way to judge, but most radios have more drive than either of those amps really wants except on Low or Medium, anyway. If you don't draw enough TOTAL current, amp plus radio to make the voltage drop, you're probably safe. And always, heat sink temperature is the real bottom line with either box. If the fins get too hot to touch, you're gonna hurt it. Period.
Put on fans, don't put on fans, use a smaller radio, turn it down to 'Low', whatever. Choose a combination that doesn't let the FIN SURFACES overheat, and you're probably gonna be okay. Besides, you'll sound better, too.
