Notes

This model was developed as a result of returning to the concept that "transistor radios should be both small and offer high performance".  The unique design enabled the radio to be folded  for carrying and then unfolded for easy operation. It was nicknamed "Newscaster".

The design of this and other models (see for example Sony TR-1818, Inno-Hit RS-580, Randix LCR-41) probably was inspired by Brionvega TS502.

sony: ICF-7800; Newscaster schaltet von selbst ein Rep.Bericht
Gerhard Härtl

Hallo

Mein ICF 7800 fing mit der Zeit an zu knacken, später schaltete er sich von selbst ein obwohl

OFF Schalter auf OFF und Timer Schalter ebenfalls auf OFF in Mittelstellung.

Ich sah mir den Schaltplan an meine Vermutung Q4 Switching Transistor 2SA772.

Radio zerlegt der Transistor befindet sich auf dem Timer Board,Spannungen gemessen C 5,7V

E 5,7V B 5,5V eigentlich müsste er sperren laut Schaltplan.

Transistor ausgelötet ersetzt durch BC 327 Radio wieder in Ordnung.

Alten Transistor mit Transistorprüfgerät überprüft elektrisch in Ordnung seltsam?

Gruss

G. Härtl
