The TK 220 was one of the first of the new styled, updated Grundig range.
It was a basic machine, half-track mono with two speeds (3¾ and 7½ ips), two heads, a single motor and a maximum reel size of 7″ (18cm).
The machine was also equipped with an automatic recording level and limiting (which could be manually overridden).
The TK220 doesn’t appear to have been readily available in either the UK or USA.
