Frede got back to me right away, and is looking forward to restoring the deck. I'll be sending it off day after tomorrow, and should have it back by the end of October.
Now the hunt has begun for a 12" ST/P arm, which it would be nice to equip it with.
I'm moving along with my idea of creating a shale (soapstone) bottom plinth. Frede liked the suggestion, writing:
"Soapstone Base.
That's a very good idea. My experience indicates that it will achieve a damping effect relative to interference from surroundings of about 10db. Which in this connection is quite a lot."
I may actually have a wider base made, where I get recesses carved for the tools of the trade (needle-brush, etc.) -- and then the plinth rises out from this base, all in one section, and in imitation of the original shape. The Rosewood section will be kept intact, but may end up not supporting the turntable.
Will keep you posted as work progresses.
I will be painting the deck with British Racing Green in the Napier tone, which corresponds well with the green stereo lights on the Beolab/Beomaster 5000.
The interior of the rosewood section extends deeper than what you see in front, and I don't want to cut that.
The bottom panel is the original B&O one, and has various info.
Top right - we see the sales sticker from FONA, which was selling articles for B&O back then. The price was DKK 1590,-
Below that is a white B&O imprint, stating that the deck has been made in Denmark, by B&O. As they've been very frank about the origin of the Thorens, I don't see that as a fib. There's a serial number for the Beogram, which is different from that of the Thorens player, and then there's a signature of quality approval.
There's also a white sticker which was probably placed there by someone servicing the unit at some point.
The square plate covers a recess that's been made for the motor. B&O probably cheated a little here, as my unit came with some foam rubber between the head of the motor and the wooden panel. Ideally, one should be absolutely certain that the motor was free of the chassis, to avoid any vibrations - a lot of the other elements of the Thorens construction (grommets, suspension of motor) are invalidated if the motor cover touches the plinth.
