About this Gig
Designing PCBs for tube preamps and Class A/AB amplifiers requires strict attention to safety, thermals, and noise floor optimization. High-voltage rails, heavy current paths, and sensitive vacuum tube grids are highly vulnerable to hum and thermal failure if routed incorrectly.I will take your schematic and create a professional, low-noise, production-ready PCB layout optimized for high-fidelity performance and structural safety.What this service covers:Tube Preamps: Proper high-voltage (B+) trace clearances, creepage distances, and optimized heater layouts to minimize AC hum.Class A & AB Amps: Extra-thick copper traces for high-current delivery and strategic layouts for chassis heatsink mounting.Thermal Management: Isolating high-heat components from sensitive signal capacitors.Star Grounding: Dedicated topologies to eliminate ground loops and ripple noise.What you will receive:Industry-standard Gerber and NC Drill filesComprehensive Bill of Materials (BOM) with part numbersClear 3D visual board rendersLet's discuss your project parameters before you place an order.

FAQ
How do you ensure the high-voltage (B+) rails on tube circuits are safe from arcing?
I design strictly around standard creepage and clearance distances based on your target operating voltages. By implementing proper trace segregation, wide physical spacing, and custom ground isolation zones, I ensure the high-voltage tracks are perfectly safe and entirely stable under continuous ope
Can you handle the high-current demands of a heavy Class A or Class AB output stage?
Yes. I calculate copper weight and trace widths specifically tailored to your circuit's maximum current draw. I place heavy-duty power components strategically to allow for direct chassis heatsink mounting, ensuring your output transistors remain well within safe thermal limits.
What do you need from me regarding vacuum tube sockets or large audio transformers?
Please provide the specific datasheets or part numbers for your tube sockets (e.g., Noval 9-pin, Octal 8-pin) and any chassis-mounted transformers. This allows me to cross-reference the mechanical dimensions and pin spacing, ensuring every footprint matches your physical components exactly.
