I have this line regulator that's good to 1200 volt amps. I'm not sure what this means to me practically. I want to run two 5 watt amps, and my quite large pedal board through it but I just don't know what it can handle. Any suggestions on how to estimate she limits in the fly? I have a 15 watt amp I might use as well instead of one of the 5 watt.
