Master 39K

I noticed a little beauty up for sale at a local auction recently;
A Bang & Olufsen Master 39K in what seemed to be perfect condition.
The thought of bidding on it soon occured to me but I somehow managed to resist
the temptation. Though not quite as good looking as this particular one, I have a
similar set in my collection already that I am really looking forward to restoring.
I've restored several basket cases in my time and it was always great fun and
very rewarding but still, it would be nice to restore a set that obviously
has been cared for to an extreme extent all of its life.
Anyway, it went to a new danish owner at a more than fair price.

A couple of days after the auction ended, I was contacted by the new owner.
He asked if I thought the radio would be safe to power up and/or which things
to check before eventually doing so.
I gave him a couple of ideas regarding what to check and how but partly
because the radio was in a showroom geographically much closer to me than
him and partly because the new owner was a bit afraid of ruining something, we
agreed that I went to the showroom and picked up the radio, brought it with me home
and gave it a good check. That would also spare the poor thing from a potentially
very dangerous trip with a courier across the country.
I was - and still am - extremely busy these days so the radio stood untouched a
couple of weeks in my humble repairshop before I could set aside time for it.
Now, the time has come, even if work on this set as well as my reporting back here
may be a little on-and-off. It's summer in Denmark, we have a heat-wave and there
are so many other things to do but I probably won't be able to leave this
wonderful thing alone.

Oh what a beautiful model. Looking forward to the rest of the thread 🙂

The first thing that struck me was the exterior condition of this radio.
It looks absolutely new !
This is very rare to see for a 70+ years old radio.
It has one scratch on the cabinets left side, looks a recent mark and it was
mentioned in the auction listing but apart from that it is unbelievably beautiful.
Not a single mark anywhere.
No fingerwear on the buttons - they are shiny and smooth as new. I never saw this
before unless polished by myself.
No fingerwear around the buttons - if buttons were ever manipulated it would
have been with the utmost care not to touch the cabinet behind them (think long nails).
A very tiny flaking to the lacquer at the rattan mesh in front of the speaker was
to be expected from the millions of tiny vibrations from the speaker cone sitting
just behind it.
And no dust have collected at the groove at the bottom of the dial glass.
Unbelieveable !
It must have been covered when not in use.

Looks in absolutely beautiful condition Martin - the sneak preview I had doesn't do it justice🤒

Chris.

Unbelievable, to see a Master 39 K in such beautiful condition.

I'll follow the thread with great interest.

Looks beautiful - I'll be following this thread with great interest.

You know we are very lucky - think of all those poor sods who hate B&O and get their kicks from drooling over microscopically small Chinese SMD components in yoo-hoo-bla-bla Digital wonderpieces.

At the backside, three service stickers reveal that this radio has indeed seen
use as it was serviced by the same repairshop in 1950, 1953 and 1956.
A repairshop in Slangerup, not very far from where I live and where the radio
was auctioned.
So this radio was definitely cherished, not only while in use but also later.
The usual marks of 40+ years of storage in the basement or in the attic, burried
under various other "useless" stuff, are non-existent here.
Note the telephone number 8 and later changing to 320, suggesting a small town with only a few phones
and the radio repairer was one of the first in this town to have a phone.

Simply wonderful. A real find for the lucky owner.

Everything looks wonderfully original, - well, there is one thing; A socket at the
bottom left corner of the rear cover is not original.
It's labeled "Telefon" (telephone), which puzzles me a bit. I'm sure the
explanation is to be found inside.
The label is held to the rear cover by two rivets, cleverly mounted
using two existing ventilation holes so as not to ruin the rear cover.
What a sense for detail.
The large round hole, where the socket is now mounted, was already there.
I've noticed it on other sets too, only they were all empty.

Why 'Telefon' then Martin????
