my friend gave me an amp that he had that stopped working and inside it looks like it has 3 resistors and 1 cap fried now i was going to replace them and see if that worked but i was wondering what power supply could i use w/o haveing to hook it up to a car. Would function generator work? or anything?
yes the power supply wires will be good enough. Just remember that while you are testing it to not turn the volume up too much. the power suplly probably doesnt put out enough juice to run a speaker at high volume.
