Designed primarily for field and studio work, the half-track Uher 4000 Report was originally released in 1961. Many variants appeared over the next few years (the 4000 L in 1965 pictured left), the 4200 stereo and the Report IC (integrated Circuit) 4200 and 4400 stereo series which were available into the 1980’s. With four playing speeds (15/16 ips to 7½ ips), this battery-operated recorder was capable of a frequency response of up to 20kHz.
The sophisticated motor control system used no less than 8 transistors, 3 diodes and a voltage reference zener diode.
