About the F2a11
The Thöress F2a11 is a handcrafted stereo all-tube integrated amplifier designed around a pair of Siemens F2a11 NOS power tubes, operated as single-ended triodes. It uses Thöress’s minimalist EHT (E/intakt H/ybrid T/riode) circuit: a single-ended, zero-global-feedback tube/MOSFET hybrid topology. A 12SN7GT double triode serves in the driver stage. It can function either as an integrated amplifier, using its two independent channel volume controls, or as a stereo power amplifier with an external line-stage/full-function preamplifier; in the latter use, the controls operate as input attenuators. It has three equal-gain line-level stereo RCA inputs selected by a rear-panel rotary switch. Output transformers and the low-noise mains transformer are made in-house; the output transformers use C-cores and permit 4, 8, or 16 ohm loudspeaker matching via secondary-terminal jumper wiring. Its low 6 W-per-channel output calls for moderate-to-high-sensitivity loudspeakers with a benign impedance load.
