The tape end does work great when recording on Beocord 9000.

Do you really need it on playback anyway?

The difference in sound between BM6000 and BM8000 is not noticeable as far as day and night.

Funny enough I got a Danish review with the headline: Its better than its big brother!

The BM8000 has many specially made elements so its not actually a big brother in that sense.

I'm currently using both BM6000 and BM8000 and despite using smaller Beovox with the BM6000 I do think the sound is great regardless of the Beomaster and configuration of Beocord,CDX or DAT player. When it comes down to basics being owner of BM6000 and BM8000 for a few years know I could live with my white edition BM6000 and CDX only.

It does appear that Tape End is a recording function - I have never tried to set it up for playback mode. I might just have a go at that one.

As for the LEDs, you can practice on any one of that range of displays which were used on many machines. I used a display from a destroyed 7700 to hone my skills and later on, tried my luck on the BC9000. Since then I have repaired two displays on the BM8000 and the same one as yours on the BM6000.

So Tape End only works in Open Rec mode? Is this normal?

As for the LED display, I am tempted but I'd like to find a bad one first from a scavenged BM 6000!

Thanks for the manual extract!

Working on the LEDs wasn't too bad a job and I have now replaced all segments in three different displays. Soldering about 40 mini segments isn't good for the eyes but the results have all been well worthwhile and fairly inexpensive, about $15 per display. Best to find a practice display first - the skills and techniques took me a while to develop.

Tape end is fairly easy to use but it takes time to wind the cassette in both directions so I never really bother with that one. Instructions are shown below in case you haven't seen them.

Hello,

geearr:
Now you can have some fun fixing the BM6000 TP8 LED display!

Oh well you know I've already looked into it but it's the led segment itself that is defective. When I have the opportunity I'll change the whole board, or send it to Martin, but this is expensive. The Beomaster was re-capped. It sounds gorgeous. The Beogram 8000 has a Soundsmith SMMC20EN. The CDX I got for very little outlay because of the defective display (fixed). I'm very tempted by a BM 8000 but I'm not sure it will actually sound any better!

Anyway I spent the whole afternoon yesterday listening to the Beocord 9000 and I am delighted. I can't figure out how the 'Tape End' function works though.

Nice looking setup

Great setup.

The original tape should be a TDK MA-R as I understand it.

I had my Beocord 9000 since 2003 and I do love how it sounds.

A few years ago I discovered how good it records and it works very well with TDK MA-XG tapes.

I did not get a calibration tape or manual with mine but I did locate a manual a few weeks ago.

Could a new calibration tape be made?

Thank you Geoff and Martin. So this is normal.

I've made a few tapes and the result is really astounding for cassette; never have I heard such good sound from this humble medium. (I remember my 1971 Philips cassette recorder vividly—it was pure magic!) Here I used BASF Chrome II Super, not even Metal. Hiss is absolutely inaudible, contrary to my Revox. There is depth to the sound too, and it images quite well. The auto-calibration is a doddle to use and the recording really matches the original (Beogram CDX!). Distortion seems to be low, on a par with the A77. But then, given the enormous price-tag it held at the time and knowing the B&O engineers overall competence, how could this be different?

People who keep saying B&O stuff is just about looks should listen to this deck (and have a peek inside too). Is the 8004 anything as good by the way? Has anyone got the calibration tape B&O supplied?

I'm now looking forward to my mint Beocord 2200 I should take possession of on Monday...

Jacques

PS: which version of the 9000 is the best?

Here's a photo of the Beocord with her friends.

I agree, sounds about normal.

My two BC9000s both tend to run hot and make good heaters during winter. They are the hottest of all of the heat sinks in my house. Whether that is "normal" or not, I am not so sure.

Geoff

Re: Beocord 9000: no motor

chartz — Fri, 09 Apr 2010 01:37:34 GMT

Is it normal that the heatsink get quite hot, compared to a Beocord 6000 or 8000? It remains lukewarm on standby.

Can any BC 9000 owner confirm this please?

Also, is the battery still available?

Thanks.

Hello,

Sorry Martin, our messages were strangely posted the wrong way around!

I've tested the deck, and it performs brilliantly: it is indeed a Nakamichi eater!

The calibration works flawlessly and the resulting recording quality is really good, almost as good as my A77!(but then nothing compares to it, does it?)

So far so good then, but what can I expect after prolonged use? Will anything go wrong?

Check the voltage across 6C2, that's one of the caps on the rectifier board.
A negative 24V is to be expected here.

If that is OK, check the voltage on emitter of 4TR17, it should be the same -24V
If that is also OK, check the voltage on the collector of that same transistor 4TR17 and let us know.

Found it!

The 7915 was bad. The motor now turns!

More about the Beocord 9000 later...

TR1, TR2, IC1, IC2, IC3 all good. [edit: IC2 is a 7915, knackered after all]
