In this video I take a look at a Pioneer DJM 850-k with distorted inputs on ch1 and ch2. I test Line, Phono and CD inputs and they all have problems, but setting up a laptop and using the USB source it's good so this pointed to the pre amps on the Input board. Most DJM work in this way, but the model of the op amp is not always the same.

The part I replaced is a NJM212M and they are end of life, but Mouser had stock and was very quick to arrive in the UK.

Music used in this video is by LAKEY INSPIRED and is called Days Like These
