The making of my special custom-made design edition Böhm SINFONIA 480 SE

Gehaeuse Skizze

End of 2017

Photo 1 shows the first draft of the case top with measurements.
It was important to me that the design of the case is a reminder of the earlier Diamant 300CT and 350CT models. For me this design is chic and classically timeless.

January 2018

My brother is a Master carpenter with his own carpentry workshop. He built me all the case components designed and constructed to my own wishes and ideas.
Photo 2 shows the raw material (poplar wood and MDF strips to glue on) from which the feet are made.

The glued feet for the console lower part (photo 3), and the smaller ones for the bench (photo 4) in the wood press. The press is adjusted to a pressure of 2,2 kg/cm².

On photo 5 you can see the two ready trimmed boards for the lower parts of the console and the bench. The two holes in the front plate, are later used to fix the pillars on the bench.
In the rear plate for the console lower part, three holes will be made. The third

hole is necessary for a cable which will later be used to connect the two foot pedals, the four footswitches (pistons) and the 25-button pedal.

The top, which will be fixed to the rear wall of the console part, is hung up to dry after the first treatment with spray filler.
If you enlarge photo 6, you will see one of the two holes for the music desk.

Photo 7 shows the chassis for the console after treatment with spray filler. On the right side you can see the three holes where the decorative strips (on photo 10 left) are fixed.

Photo 11 shows the lower side of the console top. The wide nut is intended for mounting the upper control panel. In the left narrower nut there will be a LED strip.

This is the upper side of the console top (photo 12) with the music holder. There will be a LED strip installed in its nut as well. In the two holes in front of it the music desk will be fixed.

On photo 13 you can see the music stand attached to the console cover, both varnished.

Behind it are the aluminium boxes, which are used to transport the lower part of the console and the lower part of the bench.

June 2018

My Diamand 350 CT (the former show and concert instrument of the late Mark Shakespeare) is standing here on the still untreated steel pillars, which I had made by an art metalworker (Photo 16).
The black colour results from the fact that the pillars have not yet been ground and polished.

Photo 17 shows the console of my SINFONIA 480 SE with provisionally fixed keyboards and still empty control panels. The upper control panel is the one of a SINFONIA 480. It only serves as a "placeholder".
The upper part of the case as well as the lower part do not have the final varnishing yet. The steel columns are packed in

plastic bags to protect them from damage. They are now ground and polished.

July 2018

The individual parts of the pillars were during galvanizing. Everything was covered with 24 carat gold.
Photo 18 shows all parts covered in padding foil or protective film.

Photo 19 shows the gold pillars mounted on the console stand lower part.

The positions for the drill holes of the four pistons into the lower part are now marked and placed. In front of the lower part you can see one of the pistons. The green area is the contact board for connecting the electronics.

The four pistons ready mounted in a row. (Photo 20).

The ready varnished cabinet is already equipped with the boards for the AMADEUS Sound Systems, the preamplifier (in the carrier system), the Crystal Mixer, as well as the power supply. All cables have been installed correctly by Martin Lutz, as it should be.
The ZE board is mounted on the left side of the rear side. To the right you can

see the longish board with the audio ports. In the left corner of the case the USB hub is mounted. In the right rear corner XLR connectors for connecting two microphones are embedded in the bottom of the case (Photo 21).

After we connected the 25-button foot pedal for the first time, there was no sound from it. With a voltmeter the cause was quickly found. A contact problem on a board of the pedal electronics. (Photo 26).

Of course, they can't be missing. In the meantime, the logos to the designated places. What must be, must be.

In the background you can see my Diamond 350 CT.
