Switchcraft ¼" Mono 2-Conductor Input Jack, Isolated Make Circuit (Type 13). Includes nut and washer

Pure Tone has developed a high quality 1/4" three pole (stereo) jack using a new patented design that improves upon and offers a more reliable connection than standard 1/4" jacks. The Pure Tone design features two springs for both the tip connection, a spring for the ring, and an additional spring for the shield connection. These help to secure the plug into place and create a greater surface area connection at contact points to improve stability and signal integrity. These jacks also increase the current capability of 1/4" connections.

LT1054 switched-capacitor voltage converter with regulator in an 8 pin DIP package. The LT1054 device is a bipolar, switched-capacitor voltage converter with regulator. It provides higher output current and significantly lower voltage losses than previously available converters. An adaptive-switch drive scheme optimizes efficiency over a wide range of output currents. Total voltage drop at 100-mA output current typically is 1.1 V. This applies to the full supply-voltage range of 3.5 V to 15 V. Quiescent current typically is 2.5 mA. The LT1054 also provides regulation, a feature previously not available in switched-capacitor voltage converters. By adding an external resistive divider, a regulated output can be obtained. This output is regulated against changes in both input voltage and output current. The LT1054 can also shut down by grounding the feedback terminal.

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

High quality vactrols from Xvive. The Xvive vactrols are clones of the original Excelitas / Perkins-Elmer vactrols used in many effects pedals, synthesizers, compressors and other equipment. These vactrols feature a thick epoxy sealed casing. The VTL5C3 and VTL5C3/2 both have a steep slope, good dynamic range, a very low temperature coefficient of resistance, and a small light history memory.

This PCB is a recreation of the iss. 1 circuit board found in classic Fuzz Face pedals. When drawing the layout, multiple originals were closely referenced to ensure a proper match and fit. The copper traces are gold plated providing protection from corrosion indefinitely. This classic board fits the mounting holes on both original and reproduction Fuzz Face enclosures. There are numerous great parts choices available for this PCB.

600V solid wire. UL style 1015, rated to 105 degrees C. Perfect for new projects, rewiring electrical equipment, or use in breadboards, perfboard, and veroboard/stripboard.

The LM13700 series consists of two current controlled transconductance amplifiers, each with differential inputs and a push-pull output. The two amplifiers share common supplies but otherwise operate independently. Linearizing diodes are provided at the inputs to reduce distortion and allow higher input levels. The result is a 10-dB signal-to-noise improvement referenced to 0.5 percent THD. High impedance buffers are provided which are especially designed to complement the dynamic range of the amplifiers. The output buffers of the LM13700 differ from those of the LM13600 in that their input bias currents (and thus their output DC levels) are independent of IABC.

Carling, DPDT latching footswitch, On-On, with solder lugs. Provides a compact yet rugged solution to general purpose switch needs. Alternate action, metal construction and stiff (6-8 lb) actuation force have combined to make this switch a pillar in a variety of markets.
