This is a Emud Record Junior 196 AM/FM USA version.  A compact table top with the circuitry of the famed German Engineered Radios.  Schematic and alignment (Sams) can be found at www.Radiomuseum.org.  

  

 

 

IMG_2875.JPG (235533 bytes) IMG_2876.JPG (219056 bytes) IMG_2877.JPG (189193 bytes)Take a picture of where the speaker wires go. IMG_2878.JPG (223534 bytes) IMG_2879.JPG (234888 bytes)Original under chassis.  R17 V3 Screen bias resistor is burnt.
IMG_2880.JPG (171866 bytes)Document the cap wires. IMG_2881.JPG (154905 bytes)I think these new 47uf 450v caps will fit. IMG_2882.JPG (126157 bytes)It is handy to use pipe cutter. IMG_2883.JPG (136503 bytes)Remove the guts.   IMG_2887.JPG (104497 bytes)The 350 volt caps are larger than these 450 volt units.
IMG_2888.JPG (182225 bytes)This is the re-stuffed cap back in the chassis.  Also note the crispy critter resistor (R6 B+ line) in the FM tuner section.   IMG_2889.JPG (167598 bytes)This has been replaced with a 2 watt metal oxide resistor. This is not the first crispy resistor found.  Some thing is up.  IMG_2891.JPG (91502 bytes)Oh boy! See the ~30 amp strap across the 1 amp fuse?   IMG_2892.JPG (132216 bytes)I bet some one had a couple of shorted tubes and blew this fuse and later the two resistors when the fuse no longer opened up.   IMG_2894.JPG (188422 bytes)Checking the resistors.
IMG_2895.JPG (227629 bytes) IMG_2896.JPG (197855 bytes) This electrostatic checks good.  This capacitance is comparable to other tweeters that I have rebuilt.    A low buzz can be heard as induced by the cap checker.   wpe17.jpg (140215 bytes) Go To www.Radiomuseum.org for the whole document. IMG_2897.JPG (730189 bytes) Restored and aligned chassis.   
IMG_2898.JPG (631412 bytes)The power switch mechanics have been cleaned and lubricated.  There is some wear on the part that hold the power switch in the off position.  I would always unplug this unit when not in use.   IMG_2906.JPG (279725 bytes)The tweeter may be working now but it will soon stop.  The dark brown foam is original and hard.  If you touch it, it crumbles.  The yellow is the new soft foam.

 

IMG_2908.JPG (274279 bytes)The capacitance increased.  That indicates to me that a better connection from the contact to the diaphragm and/or the diaphragm is closer to the metal grill.  
IMG_2915.JPG (190089 bytes)The case was cleaned with Mineral Spirits.   IMG_2913.JPG (264571 bytes) IMG_2909.JPG (297033 bytes)The missing paper has been painted.   

IMG_2924.JPG (310340 bytes) 3 coats of hand rubbed paste wax.
