Restored and tuned German made Double Ray Black Dot with original aluminum reedplates and steel reeds in the keys of BC. This was made in Germany. It is in great condition overall. The Red celluloid covered wood case is in great structural shape but shows some wear. The bellows are reasonably tight but show some tape wear on the back and bottom. It has 21 treble buttons and 8 bass buttons. The original treble, chord and bass reeds are steel on aluminum plates and have the Hohner “T” or “H” marking. The original large and medium bass one way valves were all removed and replaced with new composite valves. The bass reedplates were removed, cleaned, one-way valves replaced and remounted then rewaxed onto the reedblocks. Final tuning occurs in situ with the reedblocks inside the case. The treble and chord reed valves are the modern plastic ones and are functioning fine.
As the photo shows, the metal grill has a little rust but no major dents. The grill clothes looks original. The wooden keyboard is intact with no cracks or missing pieces. Often there are cracks or entire sections missing between keys on some of these old accordions. The bass strap looks fine as do the bellows straps.
The thumb loop is intact and the instrument has shoulder strap brackets installed.
There are several improvements over the original. Modern high end instruments include a cross-bar between the treble reedblocks. I have added one here. This shifts any resonant frequencies much higher and out of human hearing range. I also added small holes in the reedblocks on the highest reeds. This is another common practice now on high end instruments to improve performance of these very high notes. I also limited the button travel on the treble side to prevent the common ‘buttons disappearing into the holes’ issue on old Hohners.
I have shifted the tuning from the factory A443Hz down to concert A440Hz so it sounds great playing along with modern instruments. I used ‘Viennese’ tuning with Plus/Minus tuning instead of Zero/Plus tuning. This is a bit more work for me but sounds better with other instruments since the average sound heard stays right on A440 pitch.
This weighs in at around 6 pounds.
Most of these older Hohner accordions are found with numerous notes out of tune, wheezing or not sounding at all. This was just fully tuned. There are 124 reeds in this instrument and every single one has been tuned.
Unlike most of the older Hohner boxes purchased on ebay, this is ready to play without further adjustment required. I repair and tune button accordions and have specialized in older Hohner button boxes.
