I have an antenna from Philips, bunny ears essentially. I can't find the power supply that came with it. It requires a 12 volt input at 100 ma. Would using a 12 volt that can output 800 ma be a bad idea. From my understanding the electronic item you use will only draw the necessary amperage and nothing more, so long as the voltage is the same there shouldn't be any issue. I just wan't to be sure before I blow the Philips antenna's circuit, seeing how the antenna isn't actually mine. Any help would be greatly appreciated.
