Synth Repair Services
SynthesizerServiceDepartment in German - via Till Kopper: "I can recommend SynthesizerServiceDepartment in Germany close to the home town of Waldorf synths. The name behind this company is Achim Lenzgen. He used to be one of the few technicians here in Germany able to fix a PPG wave in the late eighties. I had to contact him often and we shipped individual boards of my PPG waves back ad forth several time. Before he started his own business, he was the tech behind the Synthesizer Studio Bonn which used to be THE synth shop in Germany for many years."
