So, I just built up 30 new opamps for a ton of API 212s I'm rebuilding (and getting ready to build up 25 more). Just had a couple questions on Burn-in. I know that API amps and others go though a burn-in process before they ship (like lost of electronics). My question is what that process looks like. I would imagine that it would just have them powered up and running then for a period of time. Maybe running a tone through it as well? Not sure if it's really that necessary sonically, but it would be nice to know they're all running strong before I try and run a session on them.
