Gentlemen,

What appears to be the major reason for the makers of the L45W model radios to use the very high voltage range for the FW rectifier - the EZ12 in lieu of the EZ11? The tube data suggests a maximum of 500 volts.

I have noticed that the later models produced in 1949/50 have the additional speakers and the UKW tuner. . . .And in some instances the rectifier has been used for theater audio systems employing output tubes requiring noticeably higher output power

Respectfully,

Robert

Wichtiger Reparaturhinweis: Vor dem Chassisausbau muß der Lautsprecher ausgebaut werden. Bei Nichtbeachtung zerbricht das Skalenglas!
