The AM is aligned but the FM was giving me trouble, plus the original alignment instructions were in German, which I can't read and Google Translate and Deepl doesn't always work so well on technical terms.Īnyway, check the selenium bridge rectifier. I have a Nordmende that got put on the back burner. Many avoid these '50s German radios for many reasons but I think they sound great after some work.
the rebuilt electrostatic speaker may not put out much sound but certainly adds to the sound quality replacing all the non-polarized caps in the crossover brought all the speakers to life (Blau) be careful with the complex dial cord(s) and antenna cord, frequently a very complex setup cleaning the switches is a chore because of their inaccessibility This is what I found out when replacing the components. found great topics on how to rebuild a electrostatic tweeter (EMUD) read about the European selenium rectifier and how to decide if I needed to replace it with modern silicone diodes learned how to identify German paper capacitors researched how to read the capacitor values in the schematic
This is what I did before ordering any parts or turning on the soldering iron. I've done some minor work on Grundig and Graetz models as well. While lorenz200w and many others have much more experience than me I can offer a few suggestions based on my recent work on a Blaupunkt Arkansas and EMUD Rekord Jr.
