Without the slightest possibility of ANY objectivity, I vote choice #3, sell it to Jeff. 😁

 

Thanks Henrik and Jacques for your votes (which are genuinely appreciated) and thank you Søren for thinking of me in the first place and the confidence you have in me to care for such an item.

 

Yes, I definitely vote for choice #3!

Option three also has my vote, obviously.

I vote to sell to Jeff as well.

Ricardo,

Thank you kind sir for your vote, which like Jacques’ and Henrick’s votes, means a lot. It really does.

Owning a Beolab 5000/Beomaster 5000 has become very important to me, but the opportunity to own this pair restored by Søren is extra special, because Søren is a friend.

This is an amazing group of people here at BeoWorld and I will never forget how Frede “saved” me with my Beogram 4000 providing impossible to find parts and how Martin finished the job correcting a few minor issues AND replacing the incorrect fuse.

I also greatly appreciate how Rich recommended Benny to rebuild my two “not worth repairing” Beomaster 2400 and 4500, both of which give me so much daily pleasure.

Jeff

I vote selling it to Rich at a profit.

Yikes! Rich you rascal taunting the infinitely FAIR Søren with an enticing offer of a profit.

 

Naturally, the “infinitely FAIR” comment was in no means an attempt to sway Søren’s judgment.

 

Should I feel the need to “sway” Søren, I can do a whole lot better than that! Let’s see: charming, generous, brilliant…..  Hey, I’m just getting started. 😁

 

Now where did I put that Thesaurus?

Back to the thread, only post if you have help to offer, 

I am going crazy here, I have been through all switches they all work as should, some of them a little slow to come down to 0.1-0.2 Ohms resistance but they all get there.

The only thing that works properly is the tape input (switch on/in), everything works volume, balance, filters, mono and speakers 1 and 2.

Any other input gives failures, connected a BG, stereo gives sound in right speaker, mono switchR on gives sound in both speakers, Mono R and L on gives sound in left speaker, Mono L on gives no sound in any speaker

The other inputs except tape the same. I check the inputs and wonder, Tuner and Aux is in my opinion input connections and they are pin 1 and 4, Line out is an output and that one is also pin 1 and 4.

Question: Do I have to make special cables for connections. Or is it another failure. ??? 

None of the normal, straight DIN interconnects worked for me.

I had to make special DIN cables for AUX, TUNER (actually I modified the socket within the Beomaster to what is printed on the diagram) and TAPE.

However, the PHONO socket is normally cabled.

When I say "normal" I mean the ones of later systems like Beolab 8000.

Thank you Jacques, I have used about 5 hours coming to this conclusion, the scratching noise in the left channel was a bad done solder at the emitter of TR 25 (BC109) bypassing cap 28, 2 solder points was connected by a small strand of solder, only visible with a thread counter. Tomorrow onto pin assignment.

I tested with my BG 2404 will check with my BG 1000 tomorrow, that one will be connected to the BL until I get my BG 4002 (still in McAllen TX) 

Hi Søren,

 

Good grief, I can just FEEL your frustration level. Truly, I am sorry. Very sorry.

 

Sorry too for diverting attention from the MAIN interest of this thread. Jacques was right; my interests in a Beolab 5000 should be separated from the legitimate progression of your repair progress thereof.

 

That said, thanks Jacques, as always, for being of such a great help to Søren.

 

Actually, Søren’s difficulties have served as a bit of a catharsis for me. I have a perfectly good Beomaster 1000 awaiting restoration and still I covet a Beolab 5000.

 

While not remotely in the same league, my Beomaster 1000 should be my first responsibility.

 

I have enjoyed the common interest in the Beolab 5000 bouncing in-between Søren’s restoration and my search thereof….. I rather suspect Søren has not shared a similar enthusiasm.

 

Things always look better in the morning, so perhaps I can come up with a suitable improvement with a new day and a vat of coffee.

Hi Søren,

I have a suggestion for you regarding your question above.

Please have a look in the (English) service manual of the Beolab 5000 page 9 ->12. This might help to see the signal ways in the Beolab.

You allready found one failure in the left channel (the noise problem) - I am not quit sure if this also solved the missing signal problem?

If not - according to your description your left channel is faulty of course and the problem is before the mono/stereo switch.

I would add a signal (tone) to the left input of AUX - if you like use the phono input and deal with the DIN later on.

Check this signal also arrive at the input of the preamp.

Go backwards until you find the signal again (by the use of the circuit diagram and the schematics on page 9-12).

 

Possible failures:

The wiring could be wrong.

Broken wire.

We have seen failures of the function switch (inside the switch) - difficult to repair and to find. 

This is my suggestions
