Welcome to Beoworld Saku.🙂

Although I don't have any spares, I have a 900k (like yours but with built in speakers).

One of our members Dillen (Martin) may have a spare knob, and I'm sure will reply soon.

Welcome from me as well, nice to have more Finnish members! I got started with a flea market 900 as well, and now have three of them 🙂 Unfortunately no extra knobs...

By all means post some photos of your mystery speakers, I'm sure we can find out the model. Congratulations on the 2200's as well, they are very nice little speakers and a great match for the 900.

The dial bulbs are 6.3V / 300 mA E10 socket (you will need two) and rather easy to replace, just ask if you need help with that. They have their own fuse, which was corroded in its holder in one of mine, the bulbs themselves were OK. The stereo indicator bulb is 19V / 100 mA in case that is out as well.

There are a couple of fuse holders at the side of the chassis, near the transformer, that are usually OK.
The problem one is the one mounted on the main board and it seems to be a common fault.
Fit 7V dial lamps and they will last much longer.

The knobs are not just knobs... There are many different types used on Beomaster 900.
- Some are smooth (treble/bass), others have fingergrip (volume/tuning).
- Some have a tiny pointer dot (volume/treble/bass), others don't (tuning).
- Some are in shiny chromed brass, others are in slightly dull polished aluminum. Either all are brass or all aluminum.
- Some have 6mm spindle hole, others 4mm. Both can be found on the same Beomaster.
Radiogram versions (with no easy access to the balance control screw at the rear of the chassis) have a split volume knob to allow
for setting the channels volumes individually.
If a knob was missing, a previous owner may have substituted it with another one from the same Beomaster of lesser
importance to the owner so the remaining knobs may not be in correct positions.
Let me know exactly what type you need and I'll look for it.
I have lamps too.

And I agree - we like photos !

Thanks a lot for all comments so far, I'm still in a middle of work day here, so here are some short notes:

I'll take a look on the fuses, thanks for the tips

I have a lot of bulbs (6,3V) as left-overs from my pinball repairing, maybe they'll fit

Will take fotos from the speakers, may take few days in worst case though

Also, I'll send exact details from the knob I need - from what I recall it's smooth and may have tiny pointer dot. I'll measure the weight, so that's at least sure way to say whether it's brass or aluminium (but even without taking it off I would say chromed brass)

You mystery speakers could be

Craig: negative, they are not the Beovox 1000.

I took a look more on the speaker models listed on this site and found finally similar:

Sorry, as they are now recognised, I will not hurry so much with pics. Will take pics from both of my 900s some day later...

Dillen:

The knob then:

- All knobs in device are same material, brass, chromed. about 14,2grams each, including the screw

- Knob axle diameter 6mm

- Needed knob is smooth (bass), with tiny pointer dot

Good thing - I took a googled many fotos of Beomaster 900 and picked them which had similarly located similar knobs. It looks that the knobs (in the later 900 I got) are correctly placed and only one missing - probably it has just fallen off due to loose screw... However, the 900 I got a long time ago has knobs located wrong, but fortunately it has correct knobs as well. Need to take a screwdriver and put them where they belong... 🙂

One thing more, this is not actually B&O related, but is related to old audio stuff anyway. I'm currently fixing old Sharp VZ-2500H hi-end ghettoblaster with LP-player. I bought this from a collector in a partly broken, as-is condition. It was used already for parts by someone earlier... Now it's nearly working again, but I'm still missing one knob (all these thingies seem to drop their knobs around 😕) and several screws. I have searched for the screws few weeks now and have found nothing suitable so far. The main problem is that the screws are type for connecting plastic, not metal nor wood, so their dimensions are not similar. For example any enough long screw for wood is way too thick - plastic "screw-towers" would be just torn with them... Also, as this is quite huge device the longer screws are not found from most smaller ghettoblasters. Instead, they might have been used in other audio equipment, tvs, vcrs, printers, whatever.

Here is a foto from screws:

For the longer one I would need 1-9 pieces

For the shorter one I need 1-3 pieces

The screw head is for Philips-2 screwdriver (originally).

No foto from knob yet, but is similar to bass/treble/mic volume, if someone knows this device already (Sharp VZ-2500) and has parts...

Sorry about cross-posting this Sharp-thingie, but you never know what people might have in their storages... 😮

I have a knob. Smooth chromed brass for 6mm axle and with pointer dot.
Most pinball lamps are wedge or bajonet sockets, you need E10.

Martin

Ah, Edison Miniature type socket, I might have these as well. Were used in some old game cabinets...

Anyway, the knob, I'm interested in it. I would like to buy it, but how to proceed, can you send me E-mail (you can find my E-mail address under the Contact-button) for example?

Ok, some time has passed since my last post. Anyway, I wanted to let you all know that I got both bulbs and exactly correct knob from Dillen! A very nice guy to deal with 🙂

I have now opened my Beomaster, cleaned it, washed both front panels and polished the clear plastic, cleaned bulb sockets, installed bulbs (for some reason dial bulbs were totally missing!) and put all back together.

Now it works just as it should. There are still some marks of usage in the radio and speakers, but I'm not going to do 110% restoration, some small dents and black spots (god knows from where?) belongs to over 40 years old device. And I still have the other which looks even better 🙂
