Subject: Troubleshooting the Sub Oscillator Section

From: joaopaulosilva12@...

My Sub Oscillator section is not working at all. 


What's the best way to go about troubleshooting the different components for failures on the board?


How do I measure the LFO IG00150 chip to see if its good or bad? Mind you, I am not an electronics guy so I would need detailed instructions. I don't have a technician anywhere near where I live so trying to do this solo.


Much appreciated.
