Note: I found an old page from the PCT International website in the Internet Archive Wayback Machine that shows a picture of this amplifier. The green and red dots next to NORMAL and BYPASS are just a legend printed on the label. There is just one dual-color LED slightly above and to the left of the printed dots, which is beyond the edge Marv B's picture, so we can't tell from the picture if the LED is off or green or red.
