When not listening to BBC Radio 4, more often than not we have Radio Paradise (radioparadise.com) playing....... great music selection with no banal DJ talking.

One of my favourites as well. Probably half of the stuff they play, I've never heard of before, and I like most of it! And the playback quality of the better streams is excellent.

I had my "spare part" 2000 at the office for a while before I replaced it with a BC8000. I have ceiling mounted RL60.2's over there. One of the cow-orkers test drove it one time when I wasn't around, and commented "...that thing is LOUD!". Indeed, it packs a lot more than the form factor would have you expect.

The now complete setup (of course playing a white LP ):

The Beogram finally works, but the motor is rather noisy. Guess I'll have to disassemble it once more...

Great set-up! My white BM2000 was a small-ad purchase, non working, and was restored by Martin. For some reason we can't get a reliable and strong enough FM signal where we are for the stereo decoder to work properly (usually it's off, or cuts-in with a hissy signal). I tend to use it via the tape socket with an internet radio decoder. Sounds fantastic playing into white S45's.

Several hours and a lot of swearing later:

The dial was highly annoying! I had to redo both of mine, and was ripping my hair out over why it always got stuck somewhere in the middle after I assembled the covers. The spring guide that leads the power wires to the pointer light needs to be assembled correctly, otherwise it'll sag and bind on the higher components below once you put the lid on...

Dial is finally working. I hope it stays that way...

Very cool Beomaster. I get flashes back to the late '70s.

My mom's parents had on of these and I was playing around with the big wheels. It must have laid the B&O virus early on I belive.

Alright, disregard that previous post. 14V 80mA indeed works just fine. I just shouldn't have tested it in the basement.

The dial broke again after just one week. Someone got a spare? I'm really losing my patience here...

I am currently looking for a white one, which i think looks a lot better and more valuable than black/wood. I also think the same applies for quite many B&O products. Black for some reason reminds me of plastic and audio equipment made by any other brand than B&O. :)

I have one as well with the same oissues on the master tuning dial. It is partially restored but still has a loud buzzing noise present when powered up.

Havent done a whole lot with it since I last messed with it almost a year ago. One of these days !!!!

Re: Beomaster 2000 (type 2801)

This is definitely one of the best looking pieces. And guess what, I even have the white one.

Also got the matching Beogram. All complete with manuals and delivery notes from 1976. Right from the first owner.

Took me more than half a year to restore this thing…but now I'm almost finished!

All the small things…the presets were all stuck, the keys were loose, the dial was broken (a mounting for one of the small wheels was completely broken), the cord snapped, the cord pulley broken...

And that is just the master. The Beogram had a seized motor and a stuck tonearm lift...

I tried your solution, but unfortunately 14V/80mA for the dial bulb doesn't work here. Tuning and stereo lights are very, very dim. Guess I will just get Martin's kit...

Re: Beomaster 2000 (type 2801)

Well, 14V / 80 mA seems to work just great as the dial bulb. It's bright enough but doesn't get too hot ("on" and "stereo" could be a little brighter; I guess the original spec for dial is 12-15 / 100 mA, which would allow a little more current to the other bulbs).

I even got the correct T5 glass socket bulbs. Unfortunately their leads were made from such material that they cannot be soldered. But since I had a bright moment for once, I bought also another set of leaded bulbs at the same time - a little different in physical size, but fit just as well.

And I managed to install one of the dial cords, but snapped the cord in the other machine, so I'll get lots of ground-up practice on those

In the other machine, I replaced the shorted TIP146 at the power stage (along with its fuse) and the power amp seems to be working, however the receiver is completely silent since +26V is missing. I'll start debugging the power supply tonight...

Edit: Another one done A tiny tantalum cap after the first regulator stage had mogrified itself into a 25 ohm resistor, and kept the output down. After that, it needed cleaning some trimpots to get good stereo out of the tuner, cleaning of all stuck preset trimpots, and now works like a charm. The most difficult operation turned out to be replacing the cut power cord...

Dillen:
Which key tops are missing ?

The keys missing in the other 2000 are OFF, FM and P1 (all black). The off key doesn't have the ridges in the bottom, so it's just a rectangular block of aluminum. A cheap plastic imitation could be easily made out of, umm, plastic (black acryl) If I get the rest of that machine working without too much work, I'll probably be interested in spare keys.

Actually I got the old dial lamps out of both machines! The markings didn't survive completely, but I can see "OSRAM 12-15 something", so I guess a 14 V / 80 mA would be close. Although the bulb looks exactly like the indicator bulbs, their current rating of 30 mA isn't enough for the dial - I tried. Maybe the dial bulbs have already been swapped by someone else way back?

Thanks for the help. If I can't get the indicators working correctly, I'll get the right bulbs for at least the machine I'm going to keep. Or I might just chicken out and rebuild the indicator circuit with a 7812...

Does anybody know of a Youtube video showing how they installed the god d*mn dial cords at the factory?

Mika,

Which key tops are missing ?
I have a small stock of used parts and also some keytops.
I am sure that I don't have the OFF key, though.
Being the only key coming back up by itself after being pressed,
leaving the Beomaster nice and flush when powered off, it seems to be most prone to losen and get lost.
Maybe another button can be mounted and the lettering changed to fit if the OFF button is missing.

I don't recall the original lamp specs but they are rather critical because of the (silly) way the circuit is built. It needs to be spot on for all the lamps to work correctly and still you will see the discriminator lights only faint when tuned in on a strong station.

I do recall that the dial lamp included in the kit is quite small so that it will fit inside the glass envelope of the old dial lamp, which is impossible to remove and has white difused glass. You simply cut or twist off the protruding end of the old dial lamp, pull out the innards and fit a new lamp inside. The original lamp is a T5 glass socket.

Dillen:
A lamp kit is available, containing a complete set of new lamps. The kit also fixes a couple of design glitches with regards to the tuner and lamp power supplies.

Thanks, but I think I'll try to get them locally first, as I need a pile of other stuff too, and I really want to get the chaos out of my living room floor by the weekend You'll hear from me later in case I have trouble getting them...

Is the dial lamp closer to 14V / 80 mA or 12V / 60 mA then? I see those are available in about correct (T1 or T1-1/4) format.
