Yamaha Stagepas 300 no audio - quick fix. Bad power output module part # AAX6207R

FULL REPAIR UPDATE: • Yamaha Stagepas 300 - ...
---------------------------------------------------------------------------------------
This is an emergency "repair" allowing to use the unit temporarily with just one of the two speakers. I placed an order for the failed parts:
1. SMD 1W resistor size 2512, value: 0.056 Ohm,
2. Two MOSFET transistors: STP14NF12FP
The cost of the listed replacement parts is around $10. However, the entire plug-in power module AAX6207R can be purchased as a replacement part for about $150.
