Part 008 is broken, unfortunalely. Is there any replacement? Superglue won't do I guess!

Is the center piece under the lid and its leaf spring present ?

Hello Martin,

Thank you for a very quick answer !

The lid that won't stay open is the big one (dust cover). The hinge seems to be broken...

Your conversation works fine and you have an answer regarding capacitor kit and tachodisc. Check your inbox
in the extreme top right corner of this page.

Which one of the lids won't stay open ?

Hello,

I really wanted to start a conversation with Dillen but it doesn't seem to work for me.

Anyways I have in my possession a beautiful Beogram 6006 I wish to refurbish.

The lid doesn't hold open (of course?).

What I wanted to know was if it were possible to get the cap kit and the tacho disc, and possibly any fix someone could suggest for the lid problem.

I live in France, where B&O stuff is quite common.

Thanks in advance for bothering !

Hi Martin!

My problem is the same one!

You wrote it!

"That the displays light up is no guarantee that the amplifier stages are powered. Any faults in these will cause the safety circuit to kick in. In this case, the Beomaster 8000 will power up with a series of 3-4 relay clicks rather than the normal 2, depending on the fault it may even give a brief flash of the "clipping" lamp.

The "simplest" little fault, like a bad idle current trimmer, can cause this. Grab a capacitor kit and have them replace the lot while at it."

Would you be able to help me?

Which capacitors should I exchange ?

Where can I buy it?

I am from Hungarian.

Greet the help.

Best Regards

Zoltan

Luca,

It's optical. There's a lamp in the tracking housing at the foot of the carriage.
An interrupter, operated by the tonearm, interrupts the light from the lamp towards the sensor, reflecting
the angle of the tonearm.
Normally, you cannot see the light from this lamp because it's in a closed housing to avoid ambient
light disturbing the tracking.
I'm not referring to the lamp in the tracking arm next to the tonearm. That one, together with its
lens system and sensor, merely checks for the presence and (indirectly) the size of a record.

Transport can easily break a brittle filament in a 20+ years old lamp so I suppose that could be the case here.

You have a PM regarding the tachodisc.

Hi Martin,

thanks for helping! How much would it be?

And... about the lamp. I really woulnd't think about a blown lamp (if you refer to the sensor arm's light, it works).

I thought that it could be caused by an electric sensor that "feels" the tonearm's tilt, I couldn't imagine it was optical too

Good to know: I'll tell the B&O technician. I want to bring this BG 8000 to full life as it's a very remarkable piece.

Finally, I'd need a precious opinion from you. Stated that this BG 8000 has been really well packed (it took 15 actual minutes to open the box and unwrap it), it comes from NYC. Can the shipping (via USPS) be the cause of this malfunction, even if so well packed? I need to give a feedback, so...

Thanks a lot Martin!

Hi Luca,

Welcome to Beoworld !
Thanks for signing up as a gold member, your support is greatly appreciated and I wish you best of
luck in the monthly prizedraw.

I can supply the stainless tachodisc.

The tracking problem could be caused by a blown lamp in the tracking sensor housing at the foot of
the carriage, that's by far the most common reason for this problem.

Hello Rick,

where can I order a stainless steel tacho disk like yours?

And... any idea about the following problem?

The carriage correctly scans the turntable and follows any commands given by the buttons but, while playing the record, even if the tonearm correctly moves along the groove, it doesn't give the whole carriage the signal to move with it in order to let it stay tangential to the groove.

Thanks a lot, best regards.

Hi Rick,

If the caps haven't been replaced already, they really should be.

The relays are for the soft-start and safe shutdown circuits and anything amiss here should of course be corrected.

Readymade capacitor kits are available for the Beomaster 8000, Ebay or directly from me

Uh oh, I'm afraid it's time to open up my Beomaster 8000 yet AGAIN, after 10 years: when I switch it on the relays click-click-clickclick-click-click-clickclickclick before deciding to really switch on. I guess some voltage isn't coming "on" in time, any more. Just before I start digging, please yell if you experienced this too, to point me in the right direction? I noticed that there's a "delayed relay circuit" with a direct link to the main amp's right channel, so I'll look there first.

(Is a caps set available for this apparatus maybe? I enjoyed the one for the Beogram a lot, especially with those nicely coloured pictures.)

Thanks!

What a great thread Rick. I haven't got an 8000 (yet) but I know where to come when I need to open it.
It has been a pleasure reading your posts. Thanks!

Oooh, that didn't happen to me. Not-at-all. Honestly. Fingers crossed.

Thanks for all the help, it runs absolutely fine again, and with the positive, happy, WOW! only, and unmeasured flutter only.
