The kit contains all the parts to make a great sounding NPN silicon transistor version of a ColorSound™ Tone Bender Mark II™. If you want to build a germanium transistor version, you can get your own transistors ( Small Bear carries them) and you can use them with this kit. The kit includes transistor sockets to make it easy to add your germanium transistors to the kit if you would like. the kit includes all the parts for any of the versions listed on the project page, except for the germanium transistors for the germanium transistor versions.
