Konrad Birkner † 12.08.2014, Germany - Tube collection

Below you find a part of the tube collection Konrad Birkner † 12.08.2014. As a teenager mainly repair of pre WW2 radios.Hobby became profession by graduation as an EE (Dipl.Eng.Communications). 6 years Rohde & Schwarz (Polyskop) followed by 26 Years Aerospace Avionics. Early retirement (health) at age 53 gave even more time allowance for the hobby (not the only one). Radio collecting started in 1978 when I remembered a wonderful radio I owned as a boy (and played it to death, shame!). It was a Blaupunkt VII. The collection grew, but 20 years went by - until I could proudly own my dream radio. It joined an international party of about 300 Radios: Crystal Sets (ca.70); US radios (ca.120); the 1920s; Homebrew contemporary and recent; early Superheterodynes with triodes; tiny little Japan made colorful tube radios around the latest miniature AC/DC tube generation. Please see this "in memoriam" which was the only page we displayed on his funeral day (EE). Zunächst Jugendbastler, Schwerpunkt Reparaturen von Vorkriegsgeräten, dann Hobby zum Beruf gemacht (Dipl.Ing.Nachrichtentechnik), 6 Jahre Rohde & Schwarz (Polyskop), 26 Jahre Luft- und Raumfahrtelektronik, mit 53 in Frührente = noch mehr Zeit fürs Hobby (aber nicht das einzige); Sammeln seit 1978, als der Wunsch nach einem Blaupunkt VII wieder aufkam, den ich (Oh Schande !) in jungen Jahren mal besaß und "kaputt spielte". Die Sammlung wuchs und der VII kam auch, aber erst nach über 20 Jahren. Er traf auf eine Reihe Zeitgenossen aus aller Welt. Ich sammle: USA; Detektorgeräte; 20er-Jahre; Selbstbaugeräte (original und eigene), Triodensuper, und kleine bunte Röhrenradios mit Miniatur- Netzröhren (die allerletzte Röhrenradiogeneration aus Japan). Bitte klicken Sie dieses "in memoriam", das wir am Tag seiner Beerdigung als einzige Seite des Radiomuseum.org als Wertschätzung seiner Arbeit zeigten (EE).
