I will design audio preamp pcb for mic instrument and tube circuits

Looking for custom studio-grade preamplifier hardware? I design high-performance audio preamp PCBs for microphones, instruments, phono stages, and vacuum tube hybrid electronics, engineered for ultra-low noise and pristine warmth.

Services Covered:

Mic preamps, instrument buffer stages, phono stages, and line drivers

Vacuum tube & hybrid preamp circuits with high-voltage isolation layout

Low-noise op-amp selection and discrete transistor circuit design

Shielded trace routing, star grounding, and low-hum power filtering

What You Will Receive:

Production-Ready Gerber & Drill Files

Complete Schematics (PDF & EDA Source Files)

Bill of Materials (BOM) with manufacturer part numbers

High-resolution 3D PCB Renders

I focus heavily on grounding techniques, thermal isolation, and trace geometry to eliminate ground loops, AC hum, and high-frequency noise. Tools used: KiCAD, Altium Designer, and Eagle.
