TLC274 quad op amp in a 14-pin DIP package. The TLC274 quad operational amplifier combines a wide range of input offset voltage grades with low offset voltage drift, high input impedance, low noise, and speeds approaching that of general-purpose BiFET devices. These devices use Texas Instruments silicon- gate LinCMOSTM technology, which provides offset voltage stability far exceeding the stability available with conventional metal-gate processes. The extremely high input impedance, low bias currents, and high slew rates make these cost-effective devices ideal for applications which have previously been reserved for BiFET and NFET products.

µA741 single op amp in an 8-pin DIP package. The µA741 device is a general-purpose operational amplifier featuring offset-voltage null capability. The high common-mode input voltage range and the absence of latch-up make the amplifier ideal for voltage-follower applications. The device is short-circuit protected and the internal frequency compensation ensures stability without external components. A low-value potentiometer may be connected between the offset null inputs to null out the offset voltage. Features

• Short-Circuit Protection
• Offset-Voltage Null Capability
• Large Common-Mode and Differential Voltage Ranges
• No Frequency Compensation Required
• No Latch-Up

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.

High quality non-latching relays from the Panasonic TQ series. These 5 volt relays are commonly used in pedals for true bypass switching. Relay switching can allow for a variety of options on pedal builds. Different footswitch modes can be obtained using the same momentary footswitch. Stereo switching using a standard footswitch is another possible option. Features:

• Compact low profile size
• Standard DIL spacing for easy PCB use and breadboard compatibility
• Non-Latching
• Single Coil
• 5V Coil Voltage

For a latching version, please see P-RP-TQ2-L-5V.

Single position machine pin sockets. These pressfit sockets are mounted by inserting into a PCB hole and applying some force. They stay firmly in place with tension and can then be easily soldered to the circuit board. These sockets can fit any pin spacing, such as the non-standard 0.15” spacing of the vintage-style stripboard (vs. 0.10” on standard stripboard). They can also jump rows so that they are not all in a line. The press-fit machine pin sockets are also very low profile and have a very minimal impact on the resulting look of the build. For pins sizes .015 -.025". The recommended mounting hole diameter is 0.057".

IC component sockets for dual in-line package chips (DIP, PDIP, DIL, DIPP.) These sockets feature ladder style cases with tinned stamped and formed connections.

High quality TO package transistor sockets by Mill-Max. These machine pin sockets make swapping transistors in pedals and other projects a simple process. These use a standard TO footprint so they are ready for use on PCBs with matching footprints.

20 position male pin headers with a 2.54mm (0.1”) pitch. These headers use round pins that are smaller than the standard square type and are perfect for use with IC sockets, breadboards, and machine pin sockets. The breakaway construction makes fitting them to projects simple. Features:

• Round Pin
• 20 Position
• 2.54mm Spacing
• Breakaway

High quality single row machine pin sockets made by Preci-Dip. These sockets are the break-away type and can easily snap into smaller sizes such as 5 separate transistor sockets.
