C4 installed backwards now what?

Postby charlie_vela » Wed Aug 13, 2008 7:30 pm

After completing my second a12 i had to head out of town. I ran the final tests and thought that everthing was fine until i tried to power up the unit. I heard a strange zipping noise and no signal. i quickly shut off power until i had a chance to open it up and take a look around. I noticed that U4 and U5 were very hot and the voltages across pin 3 and 4 of the op amp were not right at all -1.9V i believe. I looked around and noticed that C4 was installed backwards. Did i damage the op amp or any other components? Can I flip the cap around or should i order a new one? Thanks.
