This treble boost kit can build a Dallas Arbiter RangeMaster type treble booster. The kit does not include a germanium transistor, so if you want one, you will have to source the Germanium transistor yourself. The kit does include the silicon transistor for a PNP or NPN silicon transistor Range Master and includes all the parts and materials you need to build either, including the PCB.
