Load Testing Amplifiers After Repair

[guitarkitbuilder]

I'd be interested to hear what methods/procedures other repairers recommend or follow to test an amplifier after its been repaired.  I've generally used a 1kHz tone and run the amp into a dummy load for 8 hours or so to see how it handles getting hot, but someone's probably got a better procedure.  What do you do?

It all depends upon the amp.  I prefer to burn them in using a realistic signal, usually music from my bench stereo tuned to FM radio.  A sine wave is not a real signal in that sense.   it is extremely useful for diagnostics of course, but it is a heavier burden on an amp than music.
