Description
As far as I can tell, this was identical to the TK 8 but finished in beige than the usual Grundig two-tone gray.
It does not appear to have been available in the UK/USA so probably just made for the local market.
Like the TK 8, it was a two-speed, twin-track mono machine with 5.9″ (15 cm) spool capacity and three internal speakers.
