[Milsurplus] EKB: ZS-R5, and EKB tubes & transistors

[Steve Saslow]

Many thanks to Ulrich HB9AIK! I am very poor at speaking/reading German, Czech and Polish - I apologize! I desire information, tube and transistor characteristics of the EKB receiver tubes and transistors, especially if they "cross" to types I may find in usa, or ??. At this point I know only the 3 tube types, that they are "sub-miniature" (physically like our 1U4, 3V4 etc.), filaments = 1.2 vd; the DF669 is variable mu and the DF668 is not ...and that the transistors are apparently all germanium types/not silicon, and are PNP...? taxes 73, Steve k7ew
