Sansui 9090DB Receiver Repair I - Protection Mode On

This is a video for repairing a Sansui 9090DB with protection mode on problem. The troubleshooting tactics I used on this unit is similar to the last video for repairing a Pioneer SX-3700. In this project, I have to give the credit to the website of Audiokama.org. Without this resources, I may need to do more work so I can get the unit fixed (since it is a common problem for the 9090DB). Next video I will continue on the adjustments for bias and DC offset.
