English: European Wire Recorders in the 1920s
Textophon & Dailygraph The Telegraphone was not a commercial success, but it did demonstrate that a wire recorder could be used successfully for certain applications such as office dictation and telephone recording. Several European companies in the 1920s attempted to market improved wire recorders for dictating and telephone recording purposes. These were the first magnetic recorders to use the new technology of electronics. Using the vacuum-tube electronic amplifiers that became available after World War I, these recorders could capture weak telephone signals and reproduce them with greater volume than was possible with the Telegraphone. Examples of these European machines included the "Textophone" and the "Dailygraph."Español: Grabadoras de alambre europeas de 1920
