Tube-equipped receivers from Autophon
The Swiss company Autophon was founded in Solothurn in 1922 as a manufacturer for equipment for automated telephony. In 1931, LF telephone broadcast receivers were added to the product range, radio receivers were initially manufactured under Lorenz licence. From 1935 on, the company produced radio receivers from it's own development. Autophon maintained its position in the Swiss radio market until the 1950s, but lost touch with the developments in FM broadcastin and television and failed to keep up with a sufficient market share.
Autophon was active in the commercial / military sector for even longer time, several receivers and transceivers used in the Swiss Army came from the Solothurn plants.
The telecommunication activities were merged into the company Ascom in 1987.
