Description
The Douk Audio F3 brings single-ended pure Class A vacuum tube sound right to your desktop. Equipped with 6P1 beam power pentodes and a 6N2 dual-triode preamp stage, the F3 outputs 3.2 watts per channel across 4Ω and 8Ω speaker loads. While 3.2W may look modest on paper, Class A tube power provides ample volume and lush acoustic texture for nearfield desktop monitors and high-sensitivity bookshelf speakers. An illuminated analog meter sits prominently on the aluminum top plate, providing real-time signal monitoring, while a front 3.5mm headphone output lets you switch to private late-night listening without rearranging cables.
