DFAmp

DUAL Function Amplifier


The Dual Function Amplifier (DFAmp) represents…
an ultimate implementation of a line control amplifier and a headphone amplifier, both of which functions are performed by the same minimalist vacuum tube circuit with very low output impedance. Such providing the amplifier with an outstanding ability to simultaneously drive long cable runs and headphones with an impedance as low as 50 ohms or even lower.

The DFAmp also features unique tone control facilities and a custom designed remote volume control presented with typical THÖRESS style and attention to detail. The circuit of the amplifier consists of a triode gain stage followed by a unity-gain current buffer employing a power pentode operated in triode mode with high idle current.
