     Steelman Transitape.     Portable tape recorder premium. These recorders were made in 1959 in the U.S. by "Steelman Phonograph & Radio CO., INC. MT. Vernon, NY Division of Herold Radio & Electronics Corp.". They then sell for $ 200. Dimensions 255 x 177 x 80 mm excluding protrusions. Weight 2.7 kg without batteries. Motor and amplifier are powered from different sets of batteries. To power the motor uses seven batteries of 1,5 v AA for power amplifier 6 such as batteries. Originally used mercury batteries ZM9 (1,4 v), similar to modern tanks alkaline batteries. In the tape used the coil with a diameter of 3 inches, and tape-width 1/4 inch. Interestingly, the tape moves to the right - left, rather than vice versa, as is customary in most recorders. On the top panel are two switches. One - speed switch, 1, 7/8 - 3, 3/4 inches per second. Second - control forward - backward. On the right side panel has a volume control - the recording level on the left - switch OFF - PLAY - RECORD. Next to the switch is a button lock record. Wiring collected at 7-type germanium transistors 2N405 manufactured by RCA. Transistors are inserted in a miniature sockets, built directly into the chassis of the recorder. Mounting all the electronics mounted, printed circuit boards do not. The top panel is a neon light indicating power supply. On the front panel - neon lamp indicating the recording level and the input and output connectors. Kinematics is mounted on a cast aluminum alloy chassis. In general, the tape is very much metal, and this is due to its great weight. The whole construction is very robust and reliable, all produced high quality, and looks very good. Especially a stylish leather jacket is made with metal in the finishing.
     I got a tape recorder in good working condition complete with original packaging box.

     We also know that a similar tape "Pentron Transitape" producing company "Pentron Electronic Corp., Chicago 24, Illinois USA". They are distinguished by simplified design, and different voltage motor - 3 v.
