Transistor - OC141, Germanium, SO-2 glass case, NPN
OC141 NPN germanium transistors. The OC141 is a popular NPN for fuzz pedals and boost effects. This transistor is in a glass SO-2 package with long leads commonly found on germanium transistors. The NPN polarity allows for use with standard pedal power supplies. The dot indicates the collector lead.
Transistor - BC108C, Philips, TO-18 case, NPN
BC108C NPN silicon transistors made by Philips. The BC108C is a popular NPN choice for fuzz pedals and other effects such as vintage silicon Fuzz Face builds and Big Muff clones.
