‎Reinardsynth#13 Korg i30 „no audio“ Repair

I have a Korg i30 on the bench this time. The user interface works just fine but... no audio?

Finding the culprit was easy and luckily I had the appropriate spare parts (a M5216L OpAmp and two 2SC2878 muting transistors). Got it in full working order again, and has already found a new owner as well.

A note on the 5216 and muting transistors: They are not produced anymore and hard to find which means: expensive to get and probably fakes... I had to salvage them from another board. When searching for them buy them from reputable sources, or find a donor device (I noted that the Yamaha ME/HS organs use them as well)
