To expand the functionality beyond the basic board, I designed a custom wiring layout that supports dual audio inputs (RCA and 3.5mm), selectable via a rotary input switch. The front panel also features a smooth audio-taper potentiometer for volume control, along with an on/off switch paired with an LED power indicator.
All components are housed in a metal Hammond project enclosure, allowing for a clean, durable layout with a minimalist aesthetic. The result is a simple, reliable amplifier that delivers great sound while offering a few thoughtful usability upgrades.
