This combination was
made by Heli Gerätebau, Hempel KG in Limbach-Oberfrohna/ East Germany (GDR)
in 1959/1960. This is the only stereo tube amp I know from East Germany.
There is a control unit
which is connected to the power amp through a multicore cable for audio and
The amplifier section
works with two ECL82 tubes in single ended mode. Do not expect more than 2
watts of output power.
It seems the unit was
also designed to be exported to other contries as it provides the
possibility to change the lines voltage to 110 Volts.
