Hallo Sammlerfreunde,

ich möchte mal wieder auf einen Fehler im Schaltplan hinweisen. Die Gegenkopplung von der ECL 11 rechts oben im ersten Schaltplan ist falsch gezeichnet. Das betrifft leider auch den Plan im Empfänger Vade-Mecum S.995 .  Die beiden anderen Schaltpläne im RM kann ich nicht beurteilen, da ich sie mir aus bekannten Gründen nicht heruntergeladen habe und die Quelle nicht kenne.

Herzliche Grüße

Greetings!

I have one of these Mende 172W radios in which the speaker has been disconnected.  I am having trouble understanding the connections to the field coil.

There are 4 connections and four wires going to the field.

In the picture below, I have numbered the connections.

Between 1 and 2, I measure. 3.4 K ohms.  Also 3.4 K ohms between points 3 and 4. So it seems that there are 2 windings in the field. There is no connection between the 2 fields.

Between points 5 and 6 measures 600 ohms, so that is the primary of the speaker transformer. No problem there.

Can anyone explain to me why there are these 2 fields and how they should be connected up? The schematic diagram gives a measurement of 1500 Ohms for the field.

Is it that the fields should be connected in parallel?

Sorry, but my German is not quite good enough to explain this problem.

Thanks

Peter
