1N4748A 22V zener diode in a DO-41 package. A semiconductor device that, above a certain reverse voltage(the zener value) has a sudden rise in current. If forward biased, the diode is an ordinary rectifier. When reverse biased, it exhibits a sharp break in its current-voltage graph. Voltage across the diode remains essentially constant for any further increase of reverse current.

New-old-stock Soviet silicon diodes KD521V (КД521B) in a SOD27 package. These diodes were used in EHX/Sovtek Big Muff models from Civil War to Black Russian. The KD521V is a high-speed switching diode encapsulated in hermetically sealed, leaded glass. The SOD27 packages are similar to DO-35.

1N4741A 11V zener diode in a DO-41 package. A semiconductor device that, above a certain reverse voltage(the zener value) has a sudden rise in current. If forward biased, the diode is an ordinary rectifier. When reverse biased, it exhibits a sharp break in its current-voltage graph. Voltage across the diode remains essentially constant for any further increase of reverse current.

Snap-in Lumberg panel mount barrel jack with solder lugs. This high quality jack is a similar size to the Lumberg low profile jack but easily snaps into place with no need to thread a nut inside the chassis. For use with barrel plugs with a 5.5mm external diameter and 2.1mm internal diameter.

Designed to fit over unused male barrel connectors on a daisy chain or power supply, Cable-Caps protect against short circuits that can occur when a live lead touches a metal surface. Sold in sets of three. Fits over standard 5.5 mm diameter barrel plug connectors.

Original Dunlop replacement rack for wah pedals (roll pin included: 0.77" length x 0.07" diameter - for mounting the rack to the treadle). The rack has 14 teeth and mounts to the underside of the treadle piece (rocking structure) of a wah pedal. The teeth of the rack interlock with the teeth of the wah potentiometer gear (i.e. pinion), thereby rotating the potentiometer's shaft as the treadle is rocked back and forth.

Carbon Film resistors are made by vacuum depositing a thin carbon film on a ceramic form. A good choice for applications which require a steady, low power drop. Package of 5. These resistors are perfect for pedal builders! 1/4 watt ± 5% tolerance EIA color coded .24" long x .08" diameter Resistance Values (5 each) 100 470 1K 2.7K 4.7K 8.2K 10K 22K 33K 47K 100K 150K 220K 470K 560K 1M

OPA134 single op amp in an 8-pin DIP package. The OPA134 series 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 OPA134 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 OPA134 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.

Dual wide-bandwidth LF353 opamps in an 8-pin DIP package. The LF353 offers a high input impedance and 3MHz bandwidth.
This LF353 device is a low-cost, high-speed, JFET input operational amplifier with very low input offset voltage. It requires low supply current yet maintains a large gain-bandwidth product and a fast slew rate. In addition, the matched high-voltage JFET input provides very low input bias and offset currents.

Dual Operational Amplifier. The NJM4558 (JRC4558) 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

CD4016B Series types are quad bilateral switches intended for the transmission or multiplexing of analog or digital signals. Each of the four independent bilateral switches has a single control signal input which simultaneously biases both the p and n device in a given switch on or off. Features:

• 20-V digital or ± 10-V peak-to-peak switching
• 280- typical on-state resistance for 15-V operation
• Switch on-state resistance matched to within 10 typ. over 15-V signal-input range
• High on/off output-voltage ratio: 65 dB typ. @ fis = 10 kHz, RL = 10 k
• High degree of linearity: <0.5% distortion typ. @ fis = 1 kHz, Vis = 5 Vp-p, VDD–VSS
• Extremely low off-state switch leakage resulting in very low offset current and high effective off-state resistance: 100pA typ.
