P-QTC1044 Regulator - TC1044, Charge Pump DC-TO-DC Voltage Converter, 8-Pin DIP
TC1044 charge pump voltage converter in an 8 pin DIP package. The TC1044S is a pin-compatible upgrade to the Industry standard TC7660 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 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 10kHz. Frequency is increased to 45kHz when pin 1 is connected to V+.

P-PC-LED-DRV PCB - LED Driver, for Pedals and Synths
This small PCB is a simple way to add an indicator light that pulses to the rate of LFOs and clocks used in pedals, synthesizers, and other equipment. Simply connect the positive supply voltage to V+, ground to GND, and the output of a positive signal (0 to V+) such as an LFO or clock to the IN pad. The trimmer can adjust how the LED reacts to the signal. Fully clockwise it will simply pulse on and off when paired with a strong signal. If the signal is a sine, triangle, or any other non-pulse type signal, adjusting the trimmer counter clockwise can dial in settings that follow the shape of the waveform, brightening and dimming with the changing voltage. For certain dual op-amp LFOs in effect pedals, the signal may not go low enough to turn the LED fully off.

P-QTL071 Op-Amp - TL071, Single, Low-Noise, JFET-input, 8-Pin DIP
TL071 single op amp in an 8-pin DIP package. The TL07xx JFET-input operational amplifier family is designed to offer a wider selection than any previously developed operational amplifier family. Each of these JFET-input operational amplifiers incorporates well-matched, high-voltage JFET and bipolar transistors in a monolithic integrated circuit. The devices feature high slew rates, low-input bias and offset currents, and low offset-voltage temperature coefficient. The low harmonic distortion and low noise make the TL07xseries ideally suited for high-fidelity and audio pre-amplifier applications.

W-QP-NUT-BRASS Nut - Mod® "Top Brass", for Qingpu and other 3.5mm jacks
Mod® "Top Brass" nuts are the easiest way to upgrade your Eurorack module or other 3.5 mm application to a more regal look - we call it "Top Brass". Designed with the same outer dimensions as Qingpu knurled nuts, these round brass nuts will fit any module using Qingpu or other similar metal-bushing jacks without covering up the jack labels. As their name implies, the Mod® "Top Brass" nuts are made out of pure brass, and while they look incredible on their own, their appearance also pairs extremely well with the immersion gold used on Make Noise and other similar modules. Rather than being knurled, Top Brass nuts have a smooth outer edge for a clean look. The nuts are slotted and will work with all existing nut drivers intended for use with the knurled Qingpu-style nuts. "Top Brass" nuts use M6x0.5 threading which matches the bushing on the ubiquitous Qingpu jacks and many of their copies.

P-Q2N5135 Transistor - 2N5135, Silicon, TO-105 case, NPN
The 2N5135 is a silicon NPN transistor in a TO-105 case. This transistor is a close match to the rare 2N5133 but with higher voltage ratings and is in a larger package. The hFE range is less wide than the 2N5133 with more values in the range found in the batches used on vintage Big Muff pedals. The lower hFE range also makes these a great option for silicon fuzz pedals.
