Hohner Electronium

I have a bit less space at my home since last week and a Hohner Electronium for a company. This maybe looks like a classic accordion but it's really a 50's valve driven monophonic synthesizer with a dedicated amp. There is also a myth of Karlheinz Stockhausen using one in his early ensemble formation (or rather by his musician Harald Boje) and still some fundamental modifications to be done!
