2SC2344 BJT NPN Transistor for the MAX QB9 positions. Two are required per MAX. These transistors also work on the older revMH Diamond Buffer boards and may work for other headphone amp designs that use BJT output power transistors. If in doubt for amps other than the MAX and revMH DB boards, please contact your amp's designer to be sure.
Note: the 2SC2344 must be used with its complement, the 2SA1011.
The 2SA2344/2SA1011 BJT pair is very interesting set of transistors. Their sound may best be described as crystal clear and detailed with tight bass. They are very similar to the 2SC2238/2SA968 Toshiba pair and are a worthy replacement.
The 2SC2344/2SA101 BJT pair have what is referred to as "reverse pinout" so be sure to orient them properly. On the MAX, this is easily accomplished by mounting them on the opposite pads that are generally reserved for MOSFETs.
