30W Ultra-Linear FET Amplifier Board

An ultra-linear 30W direct-coupled FET power amplifier board targeting high-end DIY audio and engineering applications. Dimensions: 100 mm × 50 mm × 40 mm. Combines multilayer PCB with integrated metal support for thermal resilience and vibration damping. Key performance metrics: 30W output into 8 ohms, Class A operation at ±28V, harmonic distortion 100, signal-to-noise ratio >96 dB, conversion rate >30 V/µs, input sensitivity 0.5 V RMS, input impedance 10 kΩ, gain 31 dB. Recommended supply: ±24V DC; max ±28V — achievable using 20V AC full-bridge rectifier configuration. This board is intended for users who require transparency, repeatability, and measurable superiority over generic amplifier solutions. Its design foregoes cost-cutting compromises — no auto-bias circuits, no integrated protection, no proprietary ICs — instead relying on discrete FET topology and conservative operating points to deliver consistent, serviceable, and analyzable performance. It serves equally well in high-fidelity home audio projects, university electronics labs, acoustic R&D, and custom professional monitor builds — wherever fidelity, stability, and documentation-backed specifications outweigh convenience features.
