This was the German top-notch bass amp of the early sixties. It puts out 45 Watts with a pair of EL34 and sounds unbelievable with a fretless bass and a 15" cabinet.
Got this one in rather sad condition: The previous owner had painted it black (without even opening the case) and crammed 1/4" jacks in place of the original in- and outputs.
All the yellow capacitors were leaky, some of the electrolytics dry. Resistors and the rest were fine.
Special thanks to my old friend Harry Kopetzky for restoring the case and to Gerd Reinhöfer for the custom made output jacks.
