Transistor - BC181, Texas Instruments, TO-92 case, PNP
The BC181 is a general purpose PNP transistor manufactured by Texas Instruments. This low-power PNP bipolar junction transistor is in a TO-92 case.
Op-Amp - OPA2134, Dual, High Performance Audio, 8-Pin DIP
OPA2134 SoundPlus™ Audio dual op-amp with low distortion, low noise and precision. The OPA2134 are ultra-low distortion, low-noise operational amplifiers fully specified for audio applications. A true FET input stage is incorporated to provide superior sound quality and speed for exceptional audio performance. This, in combination with high output drive capability and excellent DC performance, allows for use in a wide variety of demanding applications. In addition, the OPA2134 has a wide output swing, to within 1 V of the rails, allowing increased headroom and making it ideal for use in any audio circuit. The OPA2134 SoundPlus™ audio operational amplifiers are easy to use and free from phase-inversion and the overload problems often found in common FET-input operational amplifiers. They can be operated from ±2.5-V to ±18-V power supplies.
Transistor - NOS 2N404A, TI, Germanium, Gold Lead TO-5 Case, PNP
New old stock 2N404A PNP germanium transistors manufactured by Texas Instruments. These TI 2N404A feature gold plated leads. The 2N404A is used in many fuzz pedals along with other effects. The 2N404A is the same as the 2N404 but with a higher voltage rating. This transistor is in a TO-5 package with long leads commonly found on germanium transistors.
