[QUOTE="adulbrich, post: 8564726, member: 661255"] Wow, you're diving in the deep end before you can swim. If you're not clear about soldering irons, that is a red flag to me. It would be nice to have one with varying temperature. Amp repair isn't so simple that you can just pick it up like that. Lots of it would be knowing component specs. Checking voltage at certain components and reading their nominal resistance, then comparing that to specs is what you would do to "test" amps. If you get a voltage off spec (or no voltage at all) at a component, you have to trace back further upstream to locate the problem. Reading the resistance of components is also helpful when determining fault. Having the specs for each capacitor, resistor, ect. is necessary to determine if the component is functioning properly. Also, knowing how different components affect each other is helpful. Do you know what could take out a whole line of FET's on an amp? You might need to scope a wave form. Have you ever used an oscilloscope? You will need somebody who does amp repair and has real world experience to teach you the craft. People who know how to do it won't want to share their secrets, because that would create another competitor in the business. Electronics aren't as simple as they used to be. [/QUOTE]
