dillen and jens_m, thanks a lot!

the transformer is dead, I am sure of that. I tried to measure it and the primary is blown... it is a 220-240v model

tomorrow I will search one with the correct voltages or buy one, and I'll try to bring the BM to life. i also have the tape - beocord 8000 but this one is ok because I did not use it for a very long time, and it was not plugged.

I hope nothing else is blown, but no matter what, I'll try to repair it. if this works, maybe i can help you wih some measurements for your problem...

@dillen: the problem is that I live in romania, too far away from you... and I think I can find one to fit. if not, I'll make one :D the sticker is no longer there, and i do not know why.

I've sent parts to California, South Africa, Chile, New Zealand, Iceland, Mexico, Hong Kong, Alaska and Greenland. Romania is not that far away but if you prefer to search for a suitable replacement or even make one yourself rather than grabbing an original part, that's OK with me. 🤔

I think it's alive. I tried with one transformer vith 10 an 17V on AC, and the BM went on stand by.... now... I think I can repair the original transformer. it had a metal plate on the inside.... now, i can see a rubber tube with a wire inside, that is blown. I'll try to upload a picture...

@dillen: thanks a lot, if I can't repair the original, I'll ask you for one, because the one I have, does not fit in the space :( the only one problem is for the transport... I'll ask someone how can we do, because I do not know....

got an answer by b+o the last week, that they do not stock any more spare parts for the beomaster 6000, so they don´t have the processor anymore.

perhaps you have got any other sources fo rthe ic, martin?

 

greetings

hello again...

It's a long time since my beomaster is workimg again, but now I have another problem with it :(

the freqvency display is not working well; it displays some random numbers, but, the radio is working well... I'll try first to change some capacitors, but ... with some schematics I think I'll go faster :D the second problem is that the radiator is overheating in the left side, or at least I think that, because I did not verify that until now, but... the amplifier is working fine. still... I think it's not normal...  Any help is wellcome.

thanks :D

Probably the amlifier no load current and offset trimpots.  They go bad and need replacing/resetting, this is what causes the amplifier to run too hot. While you're in there you should replace the electrolytic caps too. Ask Dillen, he can supply a cap kit with instructions and probably the right trimpots too!

The service manual, available to gold and silver members, can help you with the adjustment of the trimpots.

Good luck!

hello again!

the problem is still there, but i think i know how to fix it, but.... without a schematics is very hard. so... can anyone help me with that? i need a schematic for the entire unit, if anyone has it. plus... some wires were broken and i need to know if i put them back well..

thanks a lot 😁
