Hello,

I'm haveing a bit of trouble with my BM8000.  This just started today, but it seems that when the volume is 3.0 or above, static slowly begins to develop in the right channel only.  This happens with either Speakers 1 or 2 engaged.  As soon as I go back down to 2.8 volume, the static disappears.  Normally, this might not be too much of a problem.  However, for my listening tastes 2.8 volume is far too low.  Also, the static appears to occur only with T2 (connected to my computer, and thus iTunes) or T1.  With any of the radio presets, the static disappears.  Of course, my radio input is far louder than the T1 or T2 input.

Any help would be greatly appreciated.   

Hi and welcome to Beoworld ! 

Sounds like your Beomaster 8000 has a problem with the pre-amplifier. Could be due to aging capacitors, that's very common, but it could also be something else. I would grab a cap kit and replace the lot.

Thank you Martin.  Actually, I'm not new to Beoworld, just to the NEW Beoworld   You may recall that a couple of years ago you generously helped me with the volume control motor on my BM6000 (I'm a fan of the 6000/8000 style).  Well, the motor works great now, but the BM6000 is still at the repair shop (again, about 2 years duration) supposedly having an IC replaced.  I'm not exactly rushing them at the moment, because I am a little scared of the repair bill.

Now, back to my BM8000.  Does the static at certain volumes (and not with the radio tuner) sound consistent with bad caps?  When I originally purchased the unit about 3 years ago, the owner assured me that it had a full service with cap replacement (although I certainly don't take his word as Gospel truth). 

Do you have a cap kit I can purchase?  I suppose that replacing the caps is not a job for an amateur like me.

Thanks again.

Hi,

I'm also a great fan of the BS8000/6000 range, and owner of a BM6000...always loved the long angled console design,the red led displays,and the timber (specifically rosewood) trims. They always look totally modern and top of the line equipment.

Now just a few thoughts from a complete novice here, could the static be some sort of feedback from the PC? Have you tried perhaps a CD player or similar to the inputs and see if you get the same situation? The other thing was, you said that the output for the radio is far louder? I have an Ipod to TP1 and CD/DVD to TP2 and the output while softer than radio is not dramatically so... could this also be one of the reasons / indicator of a problem?

Anyway, good luck with it, your very lucky to have both these beautiful systems! 

The cap kit is available. Replacing the caps requires a couple of hours work as well as basic electronic skills and tools, soldering etc.
The fault could be somewhere else, we can't blame the capacitors
for all faults.
As soundchoice70 suggests, make sure to rule out the source before
attacking the Beomaster.

2 years for exchaging an IC ? That must be a new record.

Martin

Thanks!  Yes, I agree that the BS8000/6000 are wonderful designs and timelessly modern. 

I tried everything I could think of with regards to troubleshooting the problem.  The static remains with the T1 input (connected to a BC8002) and even with the T2 input (computer) disconnected.  I tried both the Speakers 1 and 2 outputs as well.  

It's interesting about your radio output.  Yes, mine is far louder that the other inputs (even with the input adjusters turned all the way up).  I wonder if the POTs are acting up as well?

Thanks Martin,

I'll check into getting the caps, but I wonder if I should let the shop finish the BM6000 job before I give them this one as well.   

They say that their waiting on a part (searching for the part for at least a year now).  Perhaps I'll find out which 'part' it is and have a try with the great folks here at Beoworld.

Yes, let us know what is missing.

In case of the CPU, ask them to check out the reset circuit before deaming out teh processor, there's a trimmer there that goes bad a.o.

I placed a call into my repair shop today and they said they'd 'call me back soon' and let me know which part it is they're after.

In the meantime, I've found a somewhat inelegant solution to my problem with the BM8000.  I simply turned up the pre-amp output setting on iTunes.  Oh well, it works for the time being.

Hi Eric,

From what I understand when you connect an Ipod and I would assume also your PC to the BM you should have the output at full. So maybe this has solved your problem?

Martin is right 2 years must be a record to service something ... I think getting the part yourself would be a wise decision....Oh and definitely let them finish the BM6000 first! 

Again.. good luck.. 

Thanks Soundchoice70,

It is more of a band-aid than a real fix.  I can still here some static in the treble if I put the iTunes preamp level all the way up.  

Also, it seems the whole kit is going to need a check.  The tape deck (BM8004) I discovered tonight does nothing when I press the play, rewind, or fast forward buttons.  It had been a while since I used it last (maybe 6 months or more). 

Maybe I just have a gremlin in the house!  I wonder why I even bother with all this old stuff anyways! 

I'm sure you can erradicate your gremlin, had one about 2 years ago, started with the washer, then dryer, fridge and then the WC! Always everything at once!

and the reason you bother... cause you probably seem to enjoy them more than if you were to buy something brand new... Kinda nice to have something 20 + years old still sounding great and not many others have!

25+ years will have any stereo asking for some kind of service. Your Beocord 8004 will need new belts and a fuse replaced if the waves go high.

Why you bother ? Because you wouldn't settle for some black japanese plastic stereo.

- And your B&O can be repaired - and it will be worth it.

Martin

Thank you both. 

You're right about it being worth it.  I was just a little frustrated when I found that the BC8004 was malfunctioning too.  I know it is really nice equipment with a timeless style.  And a little maintenance on 25 year old equipment is to be expected.

I'll put these two (BM8000 and BC8004) on the back burner until I get the BM6000 resolved.  I'll give my technician a week to reply with what part is needed before I'll bother him about it again.  Hopefully, we'll be able to get all these units settled out.
