[R-390] MTBF

[Schluensen]

Hi Bob and the List,

I have my 67EAC (Serial No.: 2283) since 1981. It cames from the German Navy in very good condition. I think it runs about 6 - 10 hours/week. One complete Alignment 1982. Every two or three years cleaning/oil/grease - thats all. Calibration is o.k., no broken tubes or something.
It works perfectly!

P.S.: Siemens E310 (Regenbogen) sold 1978 - only one bad capacitor in the Power Supply

Siemens 311e2 sold also 1978 - 2 broken Scale Lamps in the Years

These Receivers came in mint Condition from the "Auswärtiges Amt" - Foreign Office

In February I bought an Rohde&Schwarz EK07D/3 - a special Version for the Deutsche Bundespost (PTT). It was the 500kc Guard Receiver at the German Coast Station Kiel-Radio DAO from 1971 to 1981. After Cleaning and complete Alignment (with change of 1 tube) this heavy thing (65kg) runs 4 weeks/24hours without problems.
Very nice receiver - nice audio (LC-Filters...)
