The EH105 was produced during the twilight of the Italian electronic instrument industry. Located primarily in the Marque region, companies like Elka transitioned from traditional accordion building to electronic organs and synthesizers. Elka was most famous for the Warning : Internal components can hold high voltage

, but smaller home-focused units like the EH105 were essential to their catalog until the market was largely taken over by Japanese manufacturers like Casio and Yamaha.

The EH 105 uses a top-octave divider system, common in string machines of the 1970s–80s (e.g., Solina, Crumar).

Before diving into the EH105 specifically, we must understand its maker. Elka (Elettronica e Kellogg Americana) was founded in Castelfidardo, Italy—the same city famous for producing high-end accordions. Initially, Elka focused on electronic accordions, but by the late 1960s and early 1970s, they pivoted to home organs.

Unlike American organs designed for churches or jazz clubs, Elka targeted the European home market. The EH105 was born in an era when every middle-class living room aspired to have a spinet organ next to the fireplace. Elka competed by offering rich, warm transistorized tones at a fraction of the cost of a Hammond.
