A Vacuum Tube Organ
Ahlborn und Steinbach S22 This is a
completely different story than the ones we normally talk about. Today,
we are not investigating radio equipment, measurement instruments or
computers, but a musical instrument and specifically an electronic
organ; however, a masterpiece in its class. What excites me the most, is
that it is completely tube based: no transistors, no solid-state diodes,
no ICs… The organ we are talking about is a Type S22, produced by
Ahlborn u. Steinbach K.G. in Heimerdingen b. Stuttgart. I presume it was
produced between 1955 and 1960, because the company was established in
1970, and in 1960 changed its name simply in Ahlborn. Free TOC
