ECA Rudolf Staudigl - Tonfilmverstärker K2 ECA-OSR - 電子管放大器

Sound film tube amplifier K2 produced at the Rudolf Staudigl Electrical Factory in Germany. A fairly rare amplifier, which you hardly ever see anymore.
It is a mixing amplifier that besides the sound of the 16 mm sound film projector is also able to display the sound of a microphone, a turntable and tefifon. (recording) The inputs have a separate volume control. The volume button of the turntable and tefifon has a blend controller. Lots of advanced capabilities for that time! The sound colour has four settings.
The amplifier has two speaker outputs. One for 15 ohms and one for 3500 ohms. The output power is 20 watts. The amplifier works fine and all functions have been tested and found the be good. Was sold at that time often together with the Siemens film speaker box type Sf.L6.2. This will be offered elsewhere in the auction.

The amplifier will be carefully packed and presented for shipping at Post.NL with reference to Track & Trace.
