Grundig Majestic Model 4019U
This is a nice Grundig. It has stereo class A EL95 (6DL5) amplifiers. This radio however, does not have a stereo FM receiver.
I have just begun to restore this unit. All the tubes tested good except two. V3 EF89 (6DA6) 2nd FM/AM IF amp questionable and V7 EL95 (6DL5) AF output weak. The second EL95 is barely in the green.
The middle tone controls seem to be non functional. But I will trace the circuits and double check. The German designers some times will switch out or bypass some tone controls with some push button options. Or perhaps that substituted tube rendered the middle tone controls ineffective. I will see.
So far I replaced the selenium rectifier bridge with 1N4007 silicon diodes. The electrolytic caps have also been replaced. One 50uf was reading down around 34uf. So the triple can cap is defiantly on its way out. I will be adding more pictures later as the restoration progresses. Keep in touch.
* There are quite a few errors in the Sam's photofacts. Use the non export model schematic from Radiomuseum.org for proper values and FM discriminator alignment.
