Sony’s 1967 top of the range quarter-track mono tape recorder, the TC-105, featured three speeds (7½,
3¾ & 15 ips) and a maximum reel size of 7″.
The TC-105 recorder boasted several automatic functions:
‘Sony-O-matic’ automatic record level control (with a defeat switch for manual recording), an automatic tape lifter and something called a ‘Retractamatic’ pinch roller as well as having instant threading and simplified controls.
Sony’s sales pitch in a 1968 catalogue claimed it ideal for “..students, teachers. businessmen, housewives and hobbyists..”
The TC-105 had the same features and specifications as the half-track mono 104A although it was an older styling, similar in appearance to the 1964 TC-200.
