~ Correct parts and spares for your vintage Bang & Olufsen

A welcome

Through several decades, I’ve taken great pleasure in collecting, repairing and restoring Bang & Olufsen audio units.
Beomaster radio receivers, Beocord tapedecks, Beovox speakers, Beogram record- and CD players, Beolit portables, Beocenter combined units etc. and also the vintage items.
At first, I grabbed everything I could but I soon found out, that I would have to limit and concentrate and it wasn’t difficult for me to settle on the audio range with primary focus on the pre-1990 units.
This was always pure hobby, nothing else, and as hobbies are supposed to, it has brought me thousands of
hours of entertainment, finding rare units for my collection, hunting down stubborn faults, locating difficult-to-find parts
and playing with the resulting units.
The odd repair from others also found its way to my workbench, be that from right next door or from overseas.

I’d like to restore each and every single unit I can lay my hands on but, through the years, I have come
across several units that, for one reason or another, simply was too bad to restore but also too good to throw away.
I have found these units to be a valueable source of unique and model specific parts so they were meticulously
parted out, put in boxes and/or stored for use in my repairs and restoration jobs.

For me this all started long before the internet, back in the mid-1970s, so the first many years I was pretty much doing this on my own with practically no contact to others with the same hobby.
The internet eventually came around and it brought with it a lot of people with the same interest.
This was wonderful and many of these new friends with the same hobby soon found out that I had a good stash
of all sorts of parts in the dungeons.
Countless enthusiasts, private collectors, DIY’ers, dealers and even authorized repairshops have contacted me, asking for
parts and advice and I am happy to report that I’ve managed to help quite a few of them.

I rarely buy anything nowadays and, as I already said, I like to restore each and every unit possible, so please rest
assured that I am not breaking up units that could have been restored. I must admit, I may have done so 30 years ago
when the units were plentyful and parts were no problem but not today. The vast majority of parts listed on these
pages comes from units that were deemed out – most even parted out – decades ago.

My own collection counts in the thousands of units so when we speak about parts units we’re talking about a count well up in the hundreds. Some are pretty much still complete, some could be described as skeleton chassis’ while others again only have very little left but the vast majority have already been parted out, zipped up and stored as a parts pool.
To be honest, I never really got around to throwing anything away so my parts stash has grown to a level where most sane people would start to worry about me and I’ve realised that I need to part with something.
This is where the ends meet and where Beoparts came into consideration.
A blog page, where I could list parts surplus to my own needs.
This is where you are now.
Welcome!

How to buy

Let it be said right away; I’m generally flexible but most of the parts listed on these pages are very difficult to set a pricetag on.
Some parts are commonly available, others would be very difficult to find elsewhere and there are hardly any references regarding selling prices.
A few of the listed parts has an asking price stated in their description but for all other parts I would prefer to throw the ball out to the potential buyer and do it this way:
When you find one or more parts of interest, contact me and make me an offer.
Just a short note, containing information about the part(s) you are looking at, partnumber(s) will suffice, your location (country) and your offer.
I will then consider your offer and reply with an email of accept or reject.
In the case of acceptance, the email will contain information regarding shipping cost and payment methods (Paypal accepted).
In the case of reject, the email will most often contain a counteroffer for you to consider. Fair?

Note about parts conditions

≈ Leave a comment

All parts are listed and described to the best of my knowledge, capabilities and experience.

That a part has been marked as TESTED WORKING, means that the given part has been tested and found to be in working condition. The testing was either done prior to dismounting from the unit or later. If a date is stated it will be the date of testing. The date is usually stated in the form of month/year (i.e. 4/88 means april 1988).
Particularly if many years have passed since testing, it should be accepted by the new owner, that certain things would need doing to the part before using it again;
– Electrolytic capacitors can have dried out to a level where replacement is recommended. Because of their nature, containing fluids that slowly evaporate and dry out with age, it’s generally adviceable to replace electrolytic capacitors in
all things electronic every 20-25 years. Degrading to electrolytic capacitors happens regardless of use.
– Exposed contacts and open variable resistors (potentiometers and trimmers) can have oxidated. Despite perfect storage conditions, airs moisture will always attack bare metal and other conductive surfaces so exposed contacts, potentiometers, switches, relais’, pushbuttons etc. could be in need of a little exercise, a shot of contact cleaning agent or, in the case of certain types of trimmers, replacement before the part can be expected to work again.
– Mechanical things can have seized to some extent. Lubricants dry out with age, leaving potentiometer shafts, gears, motors, switch button rows and other mechanical things in need of an eventual cleaning and a fresh drop of oil.
– Wooden parts can dry out. Many woodsorts contain oil from nature. Woodsorts like teak and palisander (rosewood) will dry out with age and lose its shine when not treated with a light coat of fresh oil every five-ten years. Rub it with a little oil and it’ll be fine again. It’s a general handrule to never treat oak finishes with oil, use wax if you absolutely must do something but be careful, oak cannot easily be restored.
– Dust. All parts were stored for some time, days, weeks, months, years, decades. All parts were stored under the best possible conditions and no dust can get to the parts while storing. Most used parts are fairly clean, still there could be a little dust on a given part but that will be the “original” dust from when the part was dismounted and it will have not have damaged the part or influenced functionality.

So, that a part has been marked as TESTED WORKING doesn’t always mean that you can just fit it and you’re done.
It means that the given part is theoretically, basically and structurally working and it doesn’t have any faults other than what could have set in during storing as described above.

If a part has been marked as UNTESTED, it means just that.
It’s not some kind of “tricky” description of a defective part, it actually means that the part has NOT been tested for functionality. The given part could be defective but it could also be in fine working condition. I can’t tell.

Condition:

Mint = Like new. no marks of use or age.
Appearance is as it would be if just out of its original packing.

EX = Excellent. A used part that only bears the marks from very light use.
Cabinet parts have only microscopic marks – if any.
Electronic parts and circuit boards have no signs of bad or damaged components and no burn marks.
Previous repairs are few or none. Any previous repairs will be absolutely acceptable and decent jobs.

VG = Very Good. A used part that bears little marks from normal use.
Cabinet parts show little marks from normal use/storage. Not particularly obtrusive, typically visible only at close distance.
Electronic parts and circuit boards show signs of previous repairs but none are particularly bad jobs.

P = Present. A used part that bears heavy marks from use, wear, abuse and/or storing under less than adequate conditions.
Cabinet parts will show deep scratches, dents and/or chips, moisture effects and/or missing fragments.
Electronic parts and circuit boards will show obvious burn marks, oxidation, missing components, broken copper traces and/or other faults.
Parts in this category will only be listed if they are considered very rare and/or difficult to find.
Only of interest, really, for harvesting components or for completely rebuilding in
cases where the alternative would be no part at all.

Electronic modules and circuit boards will, unless otherwise stated, have short stumps of the previously connected
leads still on solder tags etc. to ease identification of lead colors when refitting.
Often – but not always – screws, nuts, clips and other hardware used to fit a given part will be included.
