KRK Rokit Studio Monitor Repair: distorition and pops on power on


This KRK speaker came to me with extreme distortion and popping on power on. Eventually I was able to narrow the issue down to the 4580 op amps used throughout the preamp circuit board. Not sure if there was an issue with the series of 4580's that were used in production of these "Rokit" studio monitors, but replacing the op amps made the problem go away, permanently. Each time I replaced one the problem improved; when they were all replaced it was gone!.

Below is a picture showing the effected 4580 op amps.
