schaub: Welchen Lautsprecher für meinen Goldy 3133?

Hallo Freunde,

welchen Ersatz-Lautsprecher würdet Ihr für meinen Schaub-Lorenz Goldy 3133 empfehlen?

Ich habe leider den originalen Lautsprecher nicht mehr und kenne dessen Impedanz nicht.

Danke!

 Markus

Vielen Dank für die freundliche Beratung!

Ich werde einen 4 Ohm Lautsprecher aus meinem Fundus einbauen.

  1 Dear Radio Friends

I've one Goldy II P (type 3620).
It's similar to  3133, so its schematic had been very useful to fix it.

The output transformer was repaired and some caps had been changed.
Now it is working.

BUT......:

It sounds loud (normal) in LW,MW, KW, but very low in UKW.

- A better aerial doesn't improve this a bit.
- ECC85 is not the problem (It was already checked).
- Also I can´t understand why its "Magic eye" tube shows better input signals  in  UKW  than in MW, LW,KW. It might be the opposite....Don't you agree?


Do You know this models?
Do You help me?                  Some help would be very welcome.

Best regards

Mário

Hello Mario,

Alright , this is a information,  but not good enough to give an valuation.
 
For example, on MW move the dark/ bright Border of the EM85  only 2mm, and on  FM 4mm, its clear, FM is greater ,then MW. But not an Info, for  works  FM well?

To become this info, make this:
Tune the set to an  strong FM Station, measure with an Voltmeter ( 10 M Ohm or more input resistance)  the Value on Point "1" and also on "2"  to the ground, as you can see in the  annex.


My expectation is more the 6 Volts on P1 and on P2, 50% off the Value on P1. This depends from the exact tuning of the set.  For instance, you find on P1 8,6 Volts, by fine tuning on station  the value on P2 must showed  4,3 Volts.

If not, test the four Components  marked "x".  Condensers  should have an Insulating off more then 50 M Ohm, and the "R" 200 Kohm +/- 20%.

The capacity is only important from C85 = 400pf. You can bypassed some one! Only in this case, not on insulation,  you must not soldered out!

If there all O.k. I think the only failure can bee on the switch  U2 =AM/FM (marked on small diagram), ore an shorting in this whole Area,  to ground.

If all this without failure, I don't now more,  by using only the diagram, what can bee.  

Let as wait what you find out.

if you have questions to this? ask me before.

  3 Dear Mr. Hans Knoll

Thank you for your reply.

Yes I agree you are right. That zone  must be the hot zone.
I got -24V in (1) and -0,5V in (2). Resistor and caps were right.
But... I also found that some wires were changed.They are not as  in schematic.
I think I have to read the schematic again and compare carefully the wires before I step ahead.  

Meanwille there is another information: In FM,the maximum signal display in "Magic eye" doesn't correspond to the best tunning up. In the maximum signal display the sound presents much more distortion.

Best regards

Hello Mario,
this here,  (your text) is normally when U2 is not 50% from U1.
These conditions must be performed!

Your text:
Meanwille there is another information: In FM, the maximum signal display in "Magic eye" doesn't correspond to the best tunning up. In the maximum signal display the sound presents much more distortion.


I can tell you, to fix the Ratio Detector without special knowledge, is not possible.
You can ask someone because this.

I think, the only solution is, use an "Ohmmeter" and check all the wiring around the EABC80.



For the moment that's all what I can make for you.

Show me your results.

Hans 
 

PS: Have you changed the EABC80?

Hello Mr. Hans Knoll

I had not changed the EABC80 before. Now I changed it and I got no differences.
I got some values from EABC80 pins:

Pin 1      -1,3V
pin 2      -24V
pin3       -11V
pin 6      -0,4V
pin 7       0V
pin 8       0,5 V
pin 9       69 V

Without dessoldering, was measured, in resistor R33 and R34,  500 kOhms insted of 1000 kOhm.
Some wires are not intact but they are correctly placed as in schematic.

Meanwille, Thank you for your help and time.

Hallo Mario,
 maybe , you are disappointed?

About this here: Meanwille, Thank you for your help and time.

But. this  results from you, 
I got some values from EABC80 pins:

Pin 1      -1,3V
pin 2      -24V
pin3       -11V
pin 6      -0,4V
pin 7       0V
pin 8       0,5 V
pin 9       69 V

shows me,
 there must be  an interrupt  between the 400pf Condenser and EABC80 pin #1 and #3   (redlines)




I don't now, why you have not follows  this advice in Post 4? 

I think, the only solution is, use an "Ohmmeter" and check all the wiring around the EABC80

This simple measurements ,  can bring out this failure. 


O.K. if you are have endet,   that's  all right!

Hello Mr. Hans Knoll

There is a lot of components here and a compact wire scenario. I am doing my best but I have no enough experience. For example I can't find out where  is  L36 pin, in IF component.

Sorry. Give me a little more time.
Best regards

and this:


L36 is marked, this is not the Coil from Goldy, but standard Forming.

Hello Mr. Hans Knoll

Thank you for your last post. The measurements you indicated were made. You were right, Results: OPEN CIRCUIT (pins 1 and 3).  

Now I send you one diagram and one photo of the components connected to IF.

That's why I was not able to locate pin 3 of IF. As you can see only the 200kOhms resistor is there.  The 400pF capacitor is not.



Does it means that L36 IF coil is open?

Best regards

Mário

I think or belive, the 400pf is locatet inside of the Filterbox.
This is usual, to prevend radiation of 10,7mcs in the Air and other stages of the Radio.

next:  Does it means that L36 IF coil is open?

Yes sir!  Thats right!

I have send to you on post6 a marked diagramm that shows the possibilty of an interrupt.

Now i make additional a new picture,  that shows this again.




I hoppe you see what i mean?   ;-)

  11 Hello Mr. Hans Knoll

The coil wires inside of IF were well twisted but the varnish was not enough peeled. Soldering was insufficient.
Zero Ohms contact was acheived after pressing a little bit with my fingers.
 
Right in the target !. I hope you accept my respects.

Now I have to solder everything. I'll present the results later.

1 HOUR LATER:
YES!  IT WORKS FINE. PURE SOUND!
TUNE INDICATOR IS NOW INDICATING THE RIGHT TUNE.
Thank you MR. Hans Knoll for your knowlege and great help.
 How can I do to show you my thankfulness?

Yellow arrows : 1 - twisted wires are in the opposite side of this picture. See them in next picture.  ;  2- the causer wire. 

We can also see here the 400Pf capacitor.

Hallo Mario,

you ask me,  How can I do to show you my thankfulness?

What can you do ?  Work hard with all the  Members of RM.org and bring everything to an good End like here!


Thank you also.

Hello Mr. Hans Knoll

It was for pleasant me to follow this I dialogue with Mr. Mário.  Not intending to abuse its good will and availability, by chance it does not know this radio?

I am a new member, and as pods to evidence here. I presented some works, are not many, but the time has not given for more.  Thus it would desire that all the members made it.  For example, I have a radio that it only has the model that is:  SUPERSOM, has cabinet in wood the control knobs is in wood uses the valves:  6K7G, 6Q7G, 7SJ8G, 25L6G, 25Z6G, as pods to prove in annex, that if finds in this forum:  Pods to help or some member me of the Rmorg, the year and the manufacturer?
                                             THIS HELP IS FOR ALL THE MEMBERS
