There was an additional 4.7 kΩ resistor, the 1 kΩ resistor was shorted out. There are no instructions, just a diagram. 3 unlabeled potentiometers, just "tun, sq and af" on the board. The assembly is complete, a 1 kΩ resistor must be purchased before the first test. Having worked in the electronics industry for several years, I would not recommend this kit to the average hobbyist.
