The Elka EH105 (also written as EH-105) is a rare vintage arranger synthesizer and drum machine manufactured in Italy around 1986. It is known for its "Italo Disco" sound and portable design. Key Specifications & Features
Synthesis Engine: Uses an FM synthesis section providing a variety of preset sounds.
Editing: No deep editing capabilities are available; however, users can stack or layer two sounds to create heavier arrangements.
Arranger & Sequencer: Features an Auto Bass Accompaniment with standard arranger functions like tempo, rhythm variation, and song sequencing. Connectivity: elka eh105
MIDI In/Out for external synchronization (channels often default to Ch 1 for bass/arrangements and Ch 2 for solo/orchestra). Output for an External Amplifier. Footswitch input. Hardware: Built-in internal speakers.
Dual power options via a battery compartment or external power supply. Musical Application
The EH105 is highly regarded by collectors and producers of Italo Disco, New Wave, and Synthwave. Modern sound designers often use it for one-shot samples and preset banks in digital workstations like Symphony Factory or Analog Lab V. Historical Context
Produced during the "golden era" of the Italian electronic instrument industry, the EH105 was one of the last compact efforts from Elka before the company and many of its regional peers (like Farfisa and Crumar) struggled against the rise of mass-produced Japanese digital synthesizers in the late 1980s.

I’m unable to provide a specific academic paper or full document about the Elka EH 105 (a vintage analog string synthesizer from the early 1980s) because no standard, publicly available research paper or official service manual is directly in my knowledge base.
However, I can give you a detailed technical overview that would typically be found in a service manual or a restoration paper, which you can use as a basis for your own documentation or research.
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. The Elka EH105 (also written as EH-105) is
The EH 105 was one of the few Eastern European calculators with full keystroke programming and indirect addressing — comparable to a TI-58/59, but with a simpler interface.
If you meant a specific individual feature (like how to use indirect addressing, or how to enter a program), let me know — I can give step-by-step instructions.
Here’s a concise guide to the Elka EH 105, a vintage analog string synthesizer / ensemble machine from the late 1970s / early 1980s.
Because the EH105 uses a single master oscillator, if one note is dead but others work, it is usually a key contact issue. The contacts are metal leaf springs. Over 50 years, they oxidize. Fix: Deoxit spray and a business card dragged through the contact gap.
