Telefunken Ela V1140 (Vintage) Tube Mic Amplifier

Vintage Telefunken V1140 steel tube microphone preamplifier

Incredibly rare, from the heydays of German broadcasting design.
This V1140 from the 1940s or 1950s according to my best knowledge.
It’s a relative of the fabled V41a tube preamp.
The tube complement is similar: EZ11, 2 * EF12, EF12k.
Variable gain: ca. 45 .. 60dB.
