I was working on the '83 300D clock repair via replacement of the two capacitors and noticed the resistor had gotten hot enough to scorch the board. I couldn't find a thread that gave the resistor value and was barely able to read the colors on mine. It is 120 ohm (brown-red-brown-silver). Turned out it was still ok. Replaced the capacitors and back in business.
