Prewired AA battery holder. This plastic battery holder fits a single AA battery and is a great option for vintage fuzz pedals that run on 1.5V, such as the Maestro FZ-1A.

The CD4069UB device consists of six CMOS inverter circuits. These devices are intended for all general-purpose inverter applications where the medium-power TTL-drive and logic-level-conversion capabilities of circuits such as the CD4009 and CD4049 hex inverter and buffers are not required. Features:

• Standardized symmetrical output characteristics
• Medium speed operation: tPHL, tPLH = 30 ns at 10 V (Typical)
• 100% Tested for quiescent current at 20 V
• Maximum input current of 1 µA at 18 V over full package-temperature range, 100 nA at 18 V and 25°C
• Meets all requirements of JEDEC tentative standard No. 13B, Standard Specifications for Description of B Series CMOS Devices

CD4047B consists of a gatable astable multivibrator with logic techniques incorporated to permit positive or negative edge-triggered monostable multivibrator action with retriggering and external counting options. Inputs include +TRIGGER, -TRIGGER, ASTABLE, ASTABLE\, RETRIGGER, and EXTERNAL RESET. Buffered outputs are Q\, Q and OSCILLATOR. In all modes of operation, and external capacitor must be connected between C-Timing and RC-Common terminal, and an external resistor must be connected between the R-Timing and RC-Common terminals. Astable operation is enabled by a high level on the STABLE input or a low level on the ASTABLE\ input, or both. The period of the square wave at the Q and Q\ Outputs in this mode off operation is a function of the external components employed. "True" input pulses on the ASTABLE input or "Complement" pulses on the ASTABLE\ input allow the circuit to be used as a gatable multivibrator.

Steel shank / steel mandrel blind rivets with a ⅛” diameter. Blind rivets, also referred to as pop rivets, can be used to join or fasten two components without requiring access to the backside of the panel or chassis. The installation is quick and results in a joint that can be stronger and tighter than a screw. These rivets are useful for securing tube sockets or other hardware such as battery holders on stompboxes.

LM318 single op amp in an 8-pin DIP package. The LM318 is a precision, fast operational amplifier designed for applications requiring wide bandwidth and high slew rate. They feature a factor-of-ten increase in speed over general-purpose devices without sacrificing dc performance. These operational amplifiers have internal unity-gain frequency compensation. This considerably simplifies their application because no external components are necessary for operation. However, unlike most internally compensated amplifiers, external frequency compensation may be added for optimum performance. For inverting applications, feed-forward compensation boosts the slew rate to over 150 V/µs and almost double the bandwidth. Overcompensation can be used with the amplifier for greater stability when maximum bandwidth is not needed. Further, a single capacitor can be added to reduce the settling time for 0.1% error band to under 1 µs.

TC7660S charge pump voltage converter in an 8 pin DIP package. The TC7660S device is a pin-compatible replacement for the industry standard 7660 charge pump voltage converter. It converts a +1.5V to +12V input to a corresponding -1.5V to -12V output using only two low-cost capacitors, eliminating inductors and their associated cost, size and electromagnetic interference (EMI). Added features include an extended supply range to 12V, and a frequency boost pin for higher operating frequency, allowing the use of smaller external capacitors. The on-board oscillator operates at a nominal frequency of 10 kHz. Frequency is increased to 45 kHz when pin 1 is connected to V+.
