Reviews

• Purely sonically a top device. Imho clearly better than, for example, the Kenwood KT-7020 from the same house. Meanwhile, however, he comes into the years, where component failures are not uncommon. What requires with the quite not simple circuit mostly the course to the radio and television technician versed in old equipment service and can exceed the purchase price.

Stereoplay 04/1983: As of July 1984, this was the only tuner that was classified in the "Absolute Top Class".
