I also settled the question about R300. The schematic indicates that it should be 4.7 kΩ whereas the parts list calls for a 47 kΩ resistor. I can see yellow for the 4. The violet band looks more brown to me, and the third stripe is not visible. I used an ohmmeter, and it measures about 4.9 kΩ. I’m betting that it’s a 4.7kΩ with a 10% tolerance.
