Diodes & Rectifiers

The 1N914 is a small signal diode similar to the 1N4148 and is common in many older electronics. The 1N914 is general purpose and can be used in a multitude of different applications.

A semiconductor device which passes current in the forward direction(from anode to cathode), and blocks current in the opposite direction. For extreme fast switches.

The 2N5135 is a silicon NPN transistor in a TO-105 case. This transistor is a close match to the rare 2N5133 but with higher voltage ratings and is in a larger package. The hFE range is less wide than the 2N5133 with more values in the range found in the batches used on vintage Big Muff pedals. The lower hFE range also makes these a great option for silicon fuzz pedals.

The BC183L is a general purpose NPN transistor in a TO-92 case. The BC183L is commonly used in fuzz pedals and has a reputation as a warm sounding silicon transistor for fuzz. The BC183L was used in some of the earliest silicon Fuzz Face pedals. The ECB pinout matches the arrangement on the P-PC-FUZZ-ISS2-BRN Iss. 2 PCB
