Unitra ZK140 - Sort of a Grundig

This Tape Recorder was made in the ZRK Factory in Poland - Grundig moved their production there and Unitra made their own version for the Eastern European market. The Decks were made to the Grundig design but with all Unitra parts. A sort of Mish Mash!
These are quite rare and this one was in a sad state.... Unitra resistors do seen to have problems. And i show you the correct way to change the belts.....
