Description

Situated in the German town of Schwarzwald, famous for its cuckoo clocks, the firm
of Josef Burger Söhne (Josef Burger Sons) had for years produced precision clocks and watches, moving to clockwork tape recorders in about 1950. They began making all-battery recorders in 1956 (the name Butoba
comes from Burger Tonbandgerät meaning ‘Burger Tape Recorder’).
Butoba machines were renowned for their sound and mechanical quality.
The MT5 had a massive flywheel for speed stability and a 7 x 5 inch internal speaker.
The mechanics were built to last and the recorder utilized two motors: one for the capstan and one for reel movement. The battery compartment contained eight batteries, but they weren’t connected as one would expect
– (in series).
