Notes

Stereo-NF-Verstärker, 2 Oval-Lautsprecher.

Laut Röhrenlageplan ist Loewe Luna Stereo 4733W mit der Röhre EBF81 im ZF-Verstärker bestückt. Dies ist äusserst unwahrscheinlich da die Verwendung dieser Röhre in Deutschlad nicht belegt ist. Weiterhin konnte die Existenz der EBF81 (Bilder!) bislang nicht nachgewiesen werden.

Sehr wahrscheinlich handelt es sich um einen Druckfehler, die tatsächliche Bestückung wäre dann die EBF89.

Loewe Opta Luna Stereo 5741W verwendet ein weitgehend identisches Chassis mit EBF89 im ZF-Verstärker.

loewe-opta: Luna Stereo 4733 Tube line up
Lars-G. Lundelin

Hello radio enthusiasts!

Obviously the Loewe Opta Luna Stereo 4733W is presented here with a wrong tube line up. Look at the picture inside the set, you'll find no more than 7 tubes, although 2 of them are invisible. This set is probably equipped with following tubes: ECC85 ECH81 EBF81 ECC83 2xEL84 and the EM84. In this way the tube line up will conform with the inside picture of the 4733W. Or, maybe there are 2 types of the LO Luna Stereo 4733W??

Kind regards

Lars-G.

Hello Mr. Lundelin,

please load the picture of the tube equipment to the model.
Where is this list? On the back wall? Please also a picture of the whole back wall.
Then this may be clarified.
What tube is in your device? EBF81 or EBF89?

Best regards WB.

Good Morning, Mr Bauer!

Unfortunately I'm not an owner of the set in question, but my information is based on the owner's pics of LO 4733W, recently uploaded. He also informed me that the attached pic of the "tube chart" in my former article above, is situated on inside of the back cover. If you want to see more pictures of the LO 4733, please make a search on Google with "Timon Radiosivut".

One more thing; it seem's to be nearly impossible to find a appropriate schematic diagram for this particular radio

 

Kind regards

Lars-G.
