Here Jennie Nell with her Kawai MP6 stage piano. It had a blown -15 Volt regulator on the internal power supply board. Nice keyboard to work on, easy to disassemble. It all powered up and showed a display because the main logic board was powered but there was no audio signal from the output jacks or headphones. It is all fixed now.
This is the prettiest flight case I have ever had in my shop!
