EHT MKII
The new 2023 Hybrid Triode Integrated Amplifier (EHT Integrated MKII) offers 2x20 watts of output power into a 6 ohm load combined with very low output resistance (high damping factor). Such providing excellent drive capability for loudspeakers with medium to low efficiency or with critically low impedance which may present a challenge for our all-tube single-ended triode amplifier models. While offering the same level of ultimate sonic excellence - yet without involving exotic and costly power tubes.
The F2a11 Integrated Amplifier utilizes the famous F2a11 vacuum tube in single-ended triode operation mode for an output power of 2x6 watts into a 4, 8 or 16 ohm load. The F2a11 is a power pentode of matchless built quality exclusively manufactured by SIEMENS in the 1950s and early 1960s which has been specifically designed for the most demanding industrial applications. When operated in triode
mode this extraordinary tube offers excellent sonics on par with the finest classic filamentary triodes such as 300B, 2A3, AD1 or PX25. A 12SN7GT double-triode is employed in the driver stages. The triode sections of the 12SN7GT tube are equivalent to a 6J5GT single-triode, a highly regarded classic medium-gain octal base triode with fairly low transconductance from the early times of tube electronics, unarguably one of the most linear amplification devices ever developed in the history of electronic technology.

DUAL FUNCTION PREAMPLIFIER
The THÖRESS Dual Function Amplifier (DFAmp) represents an ultimate implementation of a line control amplifier and a headphone driving amplifier. Both functions are performed by the same minimalist vacuum tube circuit with very low
output impedance. This provides 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 features unique tone control facilities (timbre registers) and a custom designed remote volume control presented with typical THÖRESS style and attention to detail.
EHT Mono Block
THÖRESS is very pleased to announce the introduction of the Hybrid Triode Mono Amplifier (EHT Monoblock), our latest achievement. The most powerful amplifier model of our product line provides 30, 40 or 50 watts of output power into a 8, 6 or 4 ohm load respectively, combined with very low output resistance (high damping factor).
Such providing excellent drive capability for loudspeakers with medium to low efficiency or with critically low impedance which may present a challenge for
our all-tube single-ended triode amplifier models. While offering the same level of ultimate sonic excellence without involving exotic and costly power tubes!
