Hello,
Here are the photos requested of my nagra III n° B 59105
Made in Prilly Notice the fast winding button, different. Please note the unconventional micro plug, amphenol, small tuckel ? Some further remarks, the banana plugs are not gold plated, (The purpose of which is to provide a contact without oxidation)
Your nagra 5858 dating before mine, seems to possess gold-plated bananas ... not logical. When the nagra is opened, one notices that no screw is assured of its possible disassembly with the red wax. Is it the same for your 5858?
I am also interested in two pictures of the interior of your first nagra III.
And you will notice the differences and similarities with a 1968 model, even pilot or kudelsky to placed this pilot circuit near the batteries because no more other places inside ...
The recording circuit is first generation.
The paint of the case is also like your darkest. I run it 30 seconds every week, it's the price to pay to keep it in shape for many more years ...and the sound is perfect !
Best regards
Antoine Martens
