Transistor - NTE123, Silicon, TO-5 case, NPN
NTE123 NPN silicon transistors. The NTE123 is a popular NPN for fuzz pedals and other effects. This transistor is in a TO-5 package. The NTE123 was used in the Texas Square Face made by Cesar Diaz, the famous amp tech who worked with Stevie Ray Vaughan and others.
Early in his career, SRV had a broken Fuzz Face pedal and took it to Cesar Diaz to have him fix it. Diaz fixed and modified the pedal and this became the foundation of his famous version which he named the Texas Square Face. The Diaz pedals often came socketed and included a set of NTE123 along with the standard pair of P-QNTE103 to experiment with the different sounds of the transistors.
