The circuit diagram gives only 6 tubes: ECC85, ECH81, EF89, EM35 or 34, EABC80 and EL84. The EBC41 is missing!

 

Maybe there are several versions of this model?

 

Thank you

Dear Georges,

Neither the schematic nor the tube list make mention of tube EBC41. Tube EBC41 is only shown at the picture of the tube location (ID=1945431), but the picture legend explains: "Druckfehler auf Bild.  EBC41 ist nicht verbaut."

In this circuit tube EABC80 is used for detection. Do you own a device with tube EBC41 ?

Best regards,

Gidi

Picture ID = 1945427  from Derek Hrychuk shows the EBC41 located right sided near by the F.M. frontend. It sits shielded on the top of an alumnium can:

Purpose: AF preamplifier for the record player equipped with an low output magnetic cartridge.

This might be the reason for the absence in the standard schematic for the set.
The picture comment has been corrected.

Update: the schematic here represents the domestic model which has been created without pictures in June 2006. This model doesn't have the PU preamplifier. Nearly 10 years later, pictures coming from a different export model for the U.S.A. have been uploaded.

Conclusion: This export model called Majestic Musical Instrument 8090 WF/3D shall be created as a new model.
