5V linear regulator with up to 1 amp of current in a TO-220 package. This style of regulator can be found in many power supplies and also modular synth circuits as well as some stomp boxes. These voltage regulators are monolithic integrated circuits designed as fixed−voltage regulators for a wide variety of applications including local, on−card regulation. These regulators employ internal current limiting, thermal shutdown, and safe−area compensation. With adequate heatsinking they can deliver output currents in excess of 1.0 A. Although designed primarily as a fixed voltage regulator, these devices can be used with external components to obtain adjustable voltages and currents.

LM741 single opamp in an 8-pin DIP package. The LM741 has been used in classic guitar pedals such as the Distortion Plus.
The LM741 series are general purpose operational amplifiers which feature improved performance over industry standards like the LM709. They are direct, plug-in replacements for the 709C, LM201, MC1439 and 748 in most applications. The amplifiers offer many features which make their application nearly foolproof: overload protection on the input and output, no latch-up when the common mode range is exceeded, as well as freedom from oscillations.

Prototyping circuit board with a standard long strip pattern where tracks run the length of the board. The long tracks are convenient for power and ground rails, and for signal buses. Strips can be cut as needed to make smaller tracks and circuit pads and the board has 0.1" hole spacing for DIP integrated circuits/ headers as well as other parts. Higher quality than traditional stripboard, the holes are drilled, not punched.

The Accu-Bell Effector offers reverb, chorus, and delay with adjustable setting and tap tempo. This module runs on 5.5V to 9.5V DC so it is easy to incorporate into effect pedal builds. Please see the attached datasheet for an example schematic.

Solid tinned copper bus wire. 105°C temperature rating, 600V.

A great digital reverb sound that easily replaces a spring reverberation unit. Stereo outputs may be summed for mono operation. Simple interface requires only input, output, +5V, and ground.

Carling mini-toggle switch, single pole/double throw, PC Pins. ¼" mounting hole diameter. 0.354" bushing length. 3-Position, On-Off-On.

General purpose low-power NPN bipolar junction transistor, used frequently in hobbyist electronic projects. This version is lead free.
For a lead free 2N3906 see P-Q2N3906-LF.

The NJM2120 is a dual operational amplifier of 2-INPUT and 1-OUTPUT with analog switch. The NJM2120 can be used as analog switch under the condition of GV=0dB, as Switch + Amp in order that each gain (A or B) can be adjusted independently. Each amplifier of the NJM2120 has the same electrical characteristics as the NJM4558. The NJM2120 is suitable for audio, video, electrical musical instrument, etc.

High quality 3.5mm (1/8") plug. Features nickel plated brass contacts, with a nickel plated zinc shell. This plug uses a crimp strain relief for use with 4 mm O.D cables.

This a high performance dual low noise operational amplifier. Compared to the standard dual operational amplifiers, such as the NJM1458, it shows better noise performance, improved output drive capability, and considerably higher small-signal and power bandwidths. it is compensated internally for voltage follower circuit. This makes the device especially suitable for application in high quality and professional audio equipment, instrumentation, control circuits, and telephone channel amplifiers Features:

• Operating Voltage = ±3V~±22V
• Small Signal Bandwidth = 10MHz typ.
• Output Drive Capability = 600Ω,10Vrms typ.
• Input Noise Voltage = 5nV/√Hz typ.
