Alfred H. Grebe was a pioneer in the field of radio broadcasting and the production of radio sets, also producing every part necessary for the assembly of his devices. Since the early 1910s, he has dedicated himself full time to experimenting with radio and in 1914 he published his first catalog in Richmond Hill and later, in 1922, he gave birth to GREBE RADIO factory & Broadcasting Station, New York. Exactly from the dawn, of his first catalog is this splendid model CR9 , of complete original Grebe manufacture and as stated on the plate: "LICENSED UNDER ARMSTRONG ... OCTOBER 06 1914 ... FOR AMATEUR OR EXPERIMENTAL USE ONLY ..."
The radio is in absolutely impeccable condition, almost unbelievable, considering its 107 years !!! Original in every part, wooden box, black Bakelite front panel, all external and internal components. The three valves (Triodes) are not present, which original composition was composed of 1) C300 Gas Detector Triode and 2) C301 Cunningham Amplifier Triode (later RCA corp.). In fact, it should be noted that on the inner face of the upper panel there is a groove, practiced in an impeccably perfect way, which allows the housing of the "pip-tops" of the three original valves. We remind you that the CR9 is a Reaction radio (with regeneration) with two wave ranges: Medium wave (OM) and long wave (OL) from 150 to 3000 Mt. Naturally the original power supply is battery and requires headphones or external amplifier with speaker for actual listening. For other technical information, extensive literature can be found online. A few years ago it was put on test by a specialized technician who had the three necessary tubes and the radio was working, as such it is sold but to be put back into operation!
