Default OP AMP tutorial, protections,...

Hi, i am looking at some basic info about OP AMP external protections, ideal power supply requirements, active protections,...

I know this info can be found on the internet, but id like to hear what you have personnaly.

Explication:

i have this machine that analyses vibrations (IRD350) , it uses several op amps (LM741, 80's machine), and i dont see any kind of protections, proper supply filtering or dc compensation. Id like to improve it a bit, as it frys some time randomly the 741's. The schematic is a bit minimalistic.

Any suggestions is welcome !!

Pat Allen
