This is the My Small Amp PCB — the circuit that kicked off my entire YouTube journey. It’s small, loud, and built around the iconic LM386 audio amplifier, capable of delivering 2–3 W of clean, crunchy, and characterful power.

This amp has been rebuilt from my original breadboard project — the same one that so many of you watched, soldered, and recreated. Now, it’s back as a professional-quality PCB, ready to bring your DIY synths, logic sound circuits, and experimental audio creations to life.

The story

“My Small Amp” was the first tutorial I ever made on my channel. It was just me, a breadboard, an LM386, and a dream of hearing my circuits finally speak. That little amplifier made all my logic synth modules — the Hex Oscillator, Quad Modulator, and beyond — come alive.

Viewers kept asking for a real PCB version… and now it’s here. Clean layout, clear silkscreen, sturdy components — the same heart, finally in a professional form.

What makes it special

• Built around the LM386 — simple, powerful, and legendary.

• 2–3 W output — perfect for powering small speakers or synth testing.

• Volume control ready — includes pads for an onboard or external potentiometer.

• Runs on 9–12 V DC — battery or adapter friendly.

• Educational & fun — great for learning about gain, biasing, and audio output stages.

• Maker-friendly — through-hole design, large pads, and intuitive layout.

• Pairs perfectly with your DIY synth modules (Hex, Quad, Sequencer, VCO…).

What you get

• 1 × My Small Amp PCB (silkscreen + drilled).

• PDF with schematic and BOM.

Who it’s for

• Makers, students, and synth builders who want a clean amp for testing.

• Fans of my early tutorials who followed the journey from breadboard to PCB.

• Anyone who wants a small, reliable amplifier that just works.
