Probleme mit der EAA91
H. P.
06.Sep.06
  1 Hallo Kollegen,

in letzter Zeit hatte ich kurz hintereinander zweimal das gleiche Problem mit einer EAA91: eine Diode war rgelrecht "platt", die Folgen für die UKW-Demodulation (es waren beides Grundig-Geräte) kann man sich vorstellen. Nun die Frage an die Leser: wem ist das noch so ergangen, ist das signifikant ?

Gruß
Holger Pflug
