The SK99 is a discrete Op-Amp that is pin compatible with the API* 2520. It is a low noise, high performance DOA that has been specially developed for audio applications.
The SK99 will give its best noise performance with low impedance source, like low ratio input transformers (1:1 to 1:5) or transformerless input.
You bring the solder (use good quality solder, 1mm diameter max).
The SK99 kit is not a kit for beginners because of the high density of components. It is recommended to people with some soldering experience.
