One of the best soundig tube radios I ever hear is this Saba Freiburg-Studio from 1963. This radio has motortuning for the stations and volume control, probebly one of the most expensive radios of his time. This is a real heavy weight of 17 kg! Tubes are: EC92, EC92, ECH81, EF89, EM84, EBF89, EF86, EF86, ECC83, EABC80, ECL80, ELL80, ELL80.
