I will design stereo audio, preamplifier, distortion, amp, mic fx loop and power pcb
RF, Microwave and Multilayer PCB Design Engineer , KiCad Altium
Hi, I'm Romilly Prescot, a BSc Electronics Engineer specializing in RF/microwave design, high-speed multilayer PCB layout and analog audio circuits. I design LNAs, PAs, amplifiers ADS simulation, Jets...
About this Gig
Need a clean, noise free audio PCB that works the first time? I design professional analog audio PCBs stereo preamplifiers, distortion/overdrive circuits, power amplifiers, mic FX loops and power supply boards fully from schematic to manufacture-ready Gerber files.
WHAT YOU GET:
- Schematic capture KiCad / Altium / EasyEDA
- PCB layout with star grounding, ground planes, shielding and short signal returns for low noise and zero hum
- Matched stereo channels with component tolerance notes
- 3D preview + BOM + pick-and-place (CPL) files
- Gerber + drill files ready to upload to JLCPCB, PCBWay or OSH Park
- Design rules checked against your fab and your enclosure size
WHY ME?
- 10+ years in analog audio and power electronics
- Boards that are quiet, stable and easy to assemble by hand
- Clear communication and fast delivery
- Free minor revisions until it is right
PERFECT FOR: guitar pedals, headphone amps, tube and solid-state preamps, mic preamps, FX loops, active crossovers, DIY hi-fi, and redesign or repair of an existing board.
Send me your schematic, a reference design or just a rough idea I will reply with a plan and a quote within a few hours.
Let's build your board.
FAQ
What file formats will I receive?
Schematic PDF, Gerber (RS-274X), NC drill, BOM, pick-and-place/CPL, and the editable project source in KiCad/Altium/EasyEDA. STEP 3D model available on request.
Can the Gerbers be uploaded straight to JLCPCB or PCBWay?
Yes. Every board is checked against your chosen fab's design rules, and I include a ready-to-upload ZIP with the correct stack-up and drill files.
Will the board be low-noise / hum-free?
Yes. I use star grounding, separate analog and power returns, ground planes, correct trace widths and star power distribution — that's the whole point of a dedicated audio layout.
Do you design from just an idea, without a schematic?
Absolutely. Describe the function and limits (voltage, current, gain) and I'll design the schematic from scratch and confirm it with you before layout.
an you copy / improve my existing PCB?
Yes send photos, a PDF or the original files and I'll redraw it, remove errors and optimize the ground path.
Do you handle tube circuits and high voltage?
Yes. I design tube preamps and high-voltage supplies with proper creepage and clearance for safety.
