Vinyl Records Collector Dog Picture

Mechanical to Electrical Recording

The early sound transcription and reproduction was solely dependant on acoustical/mechanical means. The early 1920’s saw the vacuum-tube amplifier, which was invented by the American Lee de Forest come into use this marked the transition from mechanical to electrical recording.

Synthetic Thermoplastic Resins

Microphones took over from acoustical horns, and lo and behold the development the modern 78-rpm electric phonographic amplified player, a motor-driven turntable that incorporated a record-changing device, a cartridge, and loudspeakers. These records were originally made of shellac and later of synthetic thermoplastic resins with a playing time of about four minutes that became standard. But later on as technology increased and with the discovery of the vinyl! Recording manufactures began using the vinyl substance as they found that vinyl make it much easier to produce better sound productive records!
