Description
This unit is in very good condition. The bass knob doesn’t move, but everything else works perfectly. It sounds great. This is a very rare tube receiver manufactured in 1964 by Telefunken in Germany. It was sold in North America as the Opus 5550 MX but is more commonly known as the Opus 2550 in Europe. This is the last all-tube receiver Telefunken produced before switching to transistors and also the most sought-after of German stereo receivers from this period. This unit is completely original, including all of the German-made Telefunken-labeled tubes. It works well, you are welcome for audition. The opus 5550 mx the output power is 15 watt per channel on 5 ohms speakers.
