Synth & Eurorack Parts / DIY

High quality miniature chicken head knob with set screw for smaller applications. 0.90" long nose to tail. Mini Davies 2300 clone.

A semiconductor device which passes current in the forward direction (from anode to cathode), and blocks current in the opposite direction.

High quality R82 Series box film capacitors from Kemet. These polyester film capacitors have 5mm lead spacing, a minimum voltage rating of 63VDC, and a tolerance of ±10% or better. The small size, high specifications, and radial mounting makes them an excellent choice for PCB builds of pedals, synthesizer, and other audio equipment. The R82 Series is constructed of metallized polyester film with radial leads of tinned wire. Radial leads are electrically welded to the contact metal layer on the ends of the capacitor winding. The capacitor is encapsulated with thermosetting resin in a box of material meeting the UL 94V–0 requirements.

• Voltage rating: 63 VDC Minimum
• Lead Spacing: 5 mm
• Capacitance tolerance: ±10% or better
• Operating temperature range of -55˚C to +105˚C
• RoHS compliance and lead-free terminations
• Self-healing

Metal Film resistors consist of a resistive element of an extremely thin layer of metal alloy vacuum deposited on a substrate. Precise and quiet. Package of 5. These resistors are perfect for pedal builders! 1/4 watt.

The P-K380 is a high quality Davies 1510 clone. This classic design can be found on countless pedals, synths, amps and other equipment. The set screw uses a metal insert for additional stability and durability. This knob has an infilled painted indicator and fits 1/4" (6.35mm) pot shafts. The P-K380 pairs nicely with the color matched P-K801-BRASS-X knobs.

This brass adapter sleeve converts a 6mm shaft potentiometer or 18T knurled shaft potentiometer to 1/4" shaft (6.35mm), allowing for 1/4" knobs to be used on a wider range of potentiometers. 1/4" tall.

Linear taper, vertical mount, Alpha pots with a 6.35mm shaft diameter. These 9mm pots are popular in DIY guitar pedals, synthesizers, and other projects. Mounting nut and washer included.

The FatKeys™ SSI2164 is perhaps the most flexible VCA available, with four independent channels for lowest cost-per-VCA. The user-selectable mode control allows Class A, AB, or intermediate biasing, and current inputs and outputs provide great design freedom. Ideal for voltage-controlled filters. The SSI2164 is a versatile VCA building block for high-performance audio applications. Four independent channels provide voltage control of current-mode inputs and outputs for a gain range from +20dB to –100dB, with control provided by a ground-referenced –33mV/dB constant. The SSI2164 will directly retrofit existing SSM/V2164 positions while offering improvements that include significantly lower overall distortion, on-chip protection against asymmetrical power failure, and a substantial increase of input current handling. The device offers considerable flexibility for a wide range of design goals and applications.

Hex nut for W-QP-419GR and W-QP-518MA 3.5mm jacks. See W-QP-NUT-K for the knurled, slotted version of this nut. See W-QP-WASHER for compatible washer
