Elka Concorde 402 (c. 1975)
Documentation on the Elka Concorde 402 is thin. The record shows a two-manual electronic organ from the Italian maker Elka, dated to approximately 1975. It belongs to a broad "Concorde" family that included models from the 90 up through the 810. Beyond that, the surviving sources are mostly parts listings and the occasional secondhand sale.
The most concrete technical fact is that the Concorde 402 shares a replacement chip with the Concorde 602. It's the SC0470, a TDA0470/TDA0470D substitute, also listed alongside the AY-1-5050 P. That's about as deep as the circuit-level record goes. Schematics are available from W D Greenhill & Co for £5.95, so there's probably enough service literature out there for a repair-minded owner. No detailed specifications (number of stops, voices, dimensions, weight) have surfaced in any of the sources consulted.
One owner listing described the instrument as a "vintage button organ" with a minor electronic issue affecting some tones. An estimated price of $499 has been floated for orientation, though no sales history confirms it. The instrument is held in the collection of the Royal Museums of Art and History in Brussels.
