Argomenti: 2 | Articoli: 6

Over the last few years, I’ve been slowly rebuilding a Grundig 9040

And I now just got a 8042W/ 3D whose cabinet is unfortunately beyond repair ( at least for a radio hobbyist with reduced wood work ability ) so decided to salvage it …

 

My 9040 needs a replacement speaker and I have three questions regarding a possible loudspeaker changeover   

  

1) Are the front loudspeakers the same on both 9040 and 8042 ?  can they be swapped from one to the other model ? ( Both the dynamic and static )

They look the same on both models and bear the same mark ‘Grundig 287’

2) Second question is about the working conditions and electrical characteristics of the static tweeters

On the 9040 schematics

 

 

I wonder what does ‘120v ‘ indication mean ?

I guess it’s not a DC measured voltage? could it be a rating for a possible maximum audio voltage – but it seems to be huge?

Given the static loudspeakers are connected to 350 volts supply via the divider R237 and R238

one would expect their operating bias voltage is 290 volts; but the measured bias voltage will strongly depend on the instrument used.  

 

3) About the instrument used to measure voltages ... on the schematics it says:

What is a ‘ UVA ‘ ?  is it a multimeter , like an ‘ordinary’ 20kohms/volt – or a valve voltmeter ? Forgive me for my poor understanding of german

Thanks

Kind regards

Hallo zusammen,

wer besitzt einen der folgenden Grundig Spitzen-Musikschränke?

1.) Spitzenmusikschrank (1950/51, Chassis ähnlich 495W)

2.) 9009 (1951/52)

3.) 9010 (1952/53)

4.) 9040 (1953/54)

Für eine Recherche versuche ich, einige Fragen zu klären. Insbesondere interessiert mich die jeweilige Seriennummer, der Typ des eingebauten Plattenspielers/-wechsler sowie der Typ des Drahtton-/Tonbandgeräts. Hat jemand Informationen über die Stückzahlen der einzelnen Typen oder Original-Grundig-Stromlaufpläne / Bedienungsanleitungen?

Ich bin für alle Hinweise dankbar!
