Dual Operational Amplifier. The 4558 integrated circuit is a dual high-gain operational amplifier internally compensated and constructed on a single silicon chip using an advanced epitaxial process. Combining the features of the NJM741 with the close parameter matching and tracking of a dual device on a monolithic chip results in unique performance characteristics. Excellent channel separation allows the use of the dual device in single NJM741 operational amplifier applications providing density. It is especially well suited for applications in differential-in, differential-out as well as in potentiometric amplifiers and where gain and phase matched channels are mandatory. Features:

• Operating Voltage (±4V~±18V)
• High Voltage Gain (100dB typ.)
• High Input Resistance (5MΩ typ.)
• Bipolar Technology

The LEHLE TRANSFORMER MZ is the ideal component to avoid hum loops without degrading the sound. It achieves this through galvanic isolation of low to mid impedance audio signal sources. It can be used as an input or output transformer, for balanced or unbalanced signals.

Solderless (plug-in) breadboard with 400 connection tie-points (i.e. 400 wire insertion holes) and 4 power rails. Solderless breadboards are great for building and testing new circuits because parts can be easily inserted and removed making them completely re-usable. This breadboard has a 300 tie-point IC-circuit area plus four 25 tie-point power rails. The housing is made of white ABS plastic, with a printed legend giving numbers and letters for columns and rows. The internal contacts are phosphor bronze with a plated nickel finish and a peelable adhesive tape backing is provided for attaching it to a surface. Be sure to check out the Zipwire™ jumper wire kits for use with this breadboard.

Carling submini toggle switch, DPDT, 2 position, .195" mounting hole diameter, 0.236" bushing length.

The shrink ratio on this tubing is 2 to 1, it is fungus resistant and non-corrosive. It is recommended for tightly sealing connectors, terminals, wire splices, and tool handles. It may be shrunk with heat guns, oven, etc. Comes in 6 inch lengths, quantity of 23.

Reverse audio taper (antilog), vertical mount, Alpha pots with a 6.35mm shaft diameter. These 9mm pots are poplar in DIY guitar pedals, synthesizers, and other projects. Mounting nut and washer included.

Carling mini-toggle switch, DPDT, ideal for phase switching, coil-tapping, series/parallel pickup switching in guitars.

• 0.354" bushing length
• ¼" mounting hole diameter
• Double pole/Double throw (DPDT)

Linear regulator with an adjustable voltage range from 1.2V to 37V. This regulator can supply 1.5A of current making it a great option for power supplies.

The 1N34A Germanium diode is an old standby in electronics. Widely used for detecting the rectifying efficiency or for switching on a radio, TV or stereo etc.

Replacement nut for CTS 450 series potentiometers and others.

• 3/8-32 threading
• Sold individually

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.

Very flexible, high flame retardant polyolefin heat shrink tubing. Unheated outer diameter of about 7.6 mm with a 2:1 shrink ratio. Resistant to common liquid solvents with excellent physical, chemical, and electrical performance.

Combination Drive, Nickel, 6mm, M3 metric, zinc. Designed to go through a hole or nut that is pre-tapped to form a mating thread for the screw. Phillips drive is the most common drive used and is designed to "camout" when the screw reaches optimum tightness, thus preventing damage to the screw head.

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.

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.

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