The Kora TA240 is a Class AB stereo amplifier delivering 2 × 120 W into 8 Ω and 2 × 200 W into 4 Ω, powered by Kora’s proprietary SquareTube® technology. Each channel features four triodes in combination with high-current power transistors, offering the natural smoothness of tubes with the unrestrained energy of solid-state amplification. This hybrid design eliminates phase shifts, ensures absolute stability, and delivers outstanding precision with natural dynamics, even on complex loads. Handcrafted in France, the TA240 embodies musicality, detail, and effortless power.

Square Tube Technology

In the TA240, Kora’s Square Tube Technology forms the foundation of its design. This unique circuit achieves the harmonic richness of tubes while retaining the control and efficiency of solid-state, giving the TA240 a character that feels effortless yet precise. It delivers clarity, texture, and dynamics well beyond what is expected at its price point, making it a standout in the power amplifier category.
