grundig: 5299 Stereo; Steuergerät

   I recently acquired a 5299 Grundig, it has a tuning eye on the right side of the dial, I would like to know what the small bulb indicator on the left side is. Is it suppose to operate when the stereo function is activated? The bulb on mine is burned out, where can I get one to replace it? Thank you, Ross W. Hoff

It is a 7 V / 100 mA type.

Herr Knoll was so kind to tell me:
The function is to indicate FM "AFC on". If you push the tuning knob the indication should go off. The function is activated by the key FA-AS (for German version, no idea what on Export model).
In AM mode the key switches the ferrite rod antenna on/off.

Good luck,
KoBi

Grundig 5299: Right channel volume lower than left channel
Jeff Tran

 I tried to balance by adjusting the "Balance Stereo" knob but that did not have any significant change to the volume of the right channel.  The volume of the left channel is significantly louder then the right channel in FM with a decoder, Tape and Phono input and in Stereo or Mono.  I replaced all paper capacitors.  I suspect the R1 (2x500 ohms) resistor which is the volume potentiometer or the right channel output transformer has gone bad.  How do I test the R1resistor and the output transformers? I do have the schematic (Howard Sam Photofact) and but it does not illustrate the R1 resistor or the output transformer in the schematic.  Please advice.

I suggest that you supply a signal from a tone generator (i. e. 1 kHz sine, 200 mV) to both channels of the tape input. Set tone and balance controls to mid position and adjust volume to a suitable level without clipping. Then, compare the signal levels at corresponding nodes of left and right channel amplifiers (measure with an oscilloscope, if possible) to find out where there are differences. Also, you could check the DC voltages at the valves to see if anything is abnormal (specifically, look for positive voltage at the control grids, that is a sign of leaky coupling capacitors). Note that the phase split valve has its grid leak connected to the cathode instead of ground, so in that case you have to measure the voltage across the grid leak instead of from grid to ground.

Output transformer failures are very seldom. If you want to test the transformers, first measure the DC resistances of all windings of both transformers and note any large differences (typically, ± 20 % is acceptable). To find out if there are shorted turns or a problem with the core, disconnect anything in the circuitry that might load the transformer (as far as i can see from the schematic, it is only the negative feedback network). Then, unless you have access to a good LCR meter, supply a 1 kHz sine signal of a few volts RMS from a tone generator to one speaker output of the radio, via a variable resistor. Connect two multimeters set for AC volts, one across the speaker output and one across the resistor. Adjust the resistor to get the same reading on both multimeters. Then repeat on the other speaker output and see that you get the same result. Maybe it could be a good idea to repeat at other frequencies (i. e. 100 Hz and 10 kHz) too.

Thank you Torbjorn Forsman for your hints.  With your advice I checked the inverter tube and it was in good order.  Then I checked the AF amp tube ECC83.   I was able to trace a bad coupling capacitor 0.001uF (C118 in the Sam Photofact manual) at the pin 3 of the preamp tube ECC83 (V8) leading to the speaker coil. The 6.8kOhm coupling resister was fine so I left it alone.  I am glad I did not have to replace the volume pot or the transformer.  Again, thank you for your kind advice.

  Could anyone tell me how to restring the dial cord for the broadcast band on this radio? Mine has the cord still intact, but is off the tuning gang pulley. Any help would be greatly appreciated. Ross

Our member Hans M. Knoll uploaded the cord stringing diagram for this model, many thanks! Hope, this will help you to get the AM drive working again.

grundig: Grundig 5299 . My first restoration
Joseph Christilles
15.Nov.06

Hello,  Well I have finished my first radio restoration, which is a 1961 Grundig 5299, complete with the original stereo speakers ! 

 Well let me tell you , when I got this in the mail and opened it up, my heart sank a little.   I bought this on Ebay, and was told that the cabinet was mint, and the speakers only had  little chips in the top corners and thats what the photos showed.  Well the stereo unit itself had been dropped on its end, and the tunning knob hardly worked.  The stereo speakers had been in water, there was a water line 3 inches up the sides.   This radio had a bad ELL80 tube, which you could tell just by looking at it.  The plate inside glowed a pritty red.   After asking many questions I ended up recaping the whole thing, papers and electolytics.  I had asked in the forum about electrolytic capacitor physical size, and got a lot of good feedback.  But as you will see the the pictures I went ahead a put in Sprague Atom caps,  I was able to get them in.  There were around 34 paper capacitors and 6 electrolytics that were replaced.   The unit came with some nice tubes, which were 3 ECC83 which are Valvo's with the 45 degree getter. Those tested very well with my newly purchased Precision tube tester.  I have also added 2 NOS Amperex ELL80's made in Holland. The other tubes are Buggle Boys, and Amperex made in holland tubes. 

  I used contact cleaner to clean all of the swithces and push buttons.  The dial now works like new.  I was having problems with the clutch mechanism that moved when switched from FM to SW, so I used a lubricant that is waxed base,  it dries fast and does not attract dust. Just what the doctor ordered.  Everything is smooth as silk.

   Now came time to turn it on, when I did, nothing bad happened.  The tubes all warmed up, and the ELL80 tube that had problems , no longer had problems.  The surgery was a success, and a smile came across my face.  I have been bitten by the bug. 

  Now I decided to leave the cabinet alone, and just clean it up.   It does have cracks in the laquer, but it has character, and I got it to shine very nice.  

   The speakers needed a little attention.  I had to sand the sides down, and restain.  I did not laquer the sides, instead I used tung oil.  They were a dull finish anyway.  The tops I left alone. 

  The woofers had to be refoamed so I found some and did that. Also I replaced the electrolytic caps going to the mids/tweeter assembly.  I was able to find 2 pin din connectors and 5 pin dins for the speaker connections.  The 2 pin are at the stereo and the speakers have 5 pin.

  The sound is very good and powerfull.  This radio picks up a lot of stations, and with no noise in the background, on FM..    SW is good, the only thing is, I do not get much if anything on LW. 

  I want to thank everyone who answered my questions in the forum.  It was a help.  

    The only thing I did not do is get pictures of the radio when I first got it.  I did take one of the chassis, when I pulled it out of the cabinet, but I lost it.  Thought I had saved it, but guess I did not.

 So here are some pictures of my work.

Joseph........

      Nice job with your restoration.....VERY nice.  

 Looks like you have been very careful and methodical.   I think the finish on the cabinet looks just fine.  Was the condition of the chassis when you received the radio as it is in the photos you've supplied - or did you have to do a cleanup of it ?  It looks to be in very good condition.

Once again......well done !

Hi Joseph,

The result looks GREAT !

My question: The chassis seems to bee very clean. How did you clean it?

Reagards

Hello Dennis and Ake.    The Chassis was dirty when I got in .  A lot of dust inside and the outside back side had a lot of old finger prints that did not want to come off.  I scrubbed with Brasso and 0000 steel wool.  I bought some Flitz that cleans a bunch of metals including nickle.  I used that with 0000 steel wool and  then went back over it with the cleaner and a rag..  Thats how it turned out.  I was quite happy with the results.  

 

  Stay tunned.  I am working on a 1939 RCA V-201.  It was given to me by my father-in-law.  I am keeping the cabinet as is.  Some chipping in the laquer but it shines great.    I will be posting that soon.  I also will be adding some schematics for the radio. 

 Thanks for the kind words on my work.

  Regards Joseph
