Hi Everyone! Here is a specific instrument amplifier. It covers a AD620 and a OP07. But it doesn't work now. It is a pity, I haven't its circuit diagram. Who can give some advices and detailed steps to repair it? I am a student. Thanks a lot.
You need to give more information and post to a newsgroup like comp.arch.embedded not here. Good luck.
Thank you for your advice. Have a nice day! :)
