Default Re: Frying amplifier finals... audio, not rf... I suspect a lot of amps that end up on the repair bench were self inflicted wounds?

I'm surprised that a lot of pre-drivers go bad... or were they too self inflicted?

I guess I did get one amp that failed due to poor QC/assembly. One of the leads on the STK chip broke. I didn't notice it broke until after I debugged down to the STK chip, bought a new STK chip, and I removed the old one. I think there was enough of a stub that I could have wired a jumper and reinstalled the old one, ha...
