Choose Your Capacitor Package:

• 1. Standard-Quality Ceramic(C0G/NP0 Dielectric):

  Optimized for maximum reliability, ultra-low noise, and ease of assembly. Uses premium Class-I C0G/NP0 ceramic capacitors in the critical high-frequency de-emphasis and response loops. Completely immune to soldering heat damage and microphonic distortion.

• 2. High Quality Film (MKS/MKT Metallized Polyester):

  Uses standard European-style metallized polyester film blocks throughout the audio path and response networks, offering smooth, musical vintage character and classic styling.

• 3. Vintage Premium (Authentic Styroflex / Polystyrene):

  For the vintage purist wanting a period-accurate build. Features genuine clear-cased Styroflex (polystyrene) capacitors in the high-frequency response and de-emphasis loops, matching the look and topology of the classic 1960s German originals.

What’s Included in This Kit:

• 1x Custom U87i Multi-Pattern PCB: High-quality FR4 board with clear silk-screening, optimized high-impedance isolation, and a dedicated injection test point for straightforward bench calibration.

• Complete On-Board Electronic Components: All through-hole resistors, diodes, filter capacitors, and JFET transistor.

• Switching Hardware: Jumper headers and shunt blocks for Pattern, -10dB Pad, and Low-Cut switching.

• Detailed digital build: A complete step-by-step instruction manual with photos

What You Will Need to Supply (Not Included):

To complete your microphone, you will provide your own:

• Microphone Body / Housing ( must be large enough to accommodate 38mm x 74mm PCB)

• Dual-Diaphragm Capsule (Standard center-terminated / isolated backplates4-wire K67/K87 style)

• Output Transformer (designed to accommodate Low Cost Neutrik 10/3. Higher quality 9.5:1 / BV13 style audio transformers can also be used)

All orders ship promptly with care. Happy building!
