KS 650 (1966)

One of the first Grundig consoles that I discovered in a warehouse. An amazing bass sound !
A High End console, as the technical data show. To be noted, the use of ECLL 800 tubes, masterpiece of integration (2 pentods and a triod in a single tube). They mark the turning point of the making techniques.
