This well kept walnut radio cabinet stands 9" tall and its base is 12.5x22". The front panel is a wine colored bakelite with beautifully tooled bronzed plates decorating the tuning wheels and knobs. The interior is very clean with original instruction charts intact on the back and inside lid. This is a very fine example of the last of the best TRF battery operated sets of the 1920's.

"This photo is of my own set, this is an MU-1 from late 1926, and was in my opinion the pinnacle of the Synchrophase. This set is completely original, with original dark mahogany finish and in the finest working condition. This says a great deal about Grebe's quality, as this set has had NO replacement parts since it was made." -David P. Whistler

About Alfred H. Grebe

Born in Richmond Hill, NY 1895
Died in Hollis, NY 1935

"Radio Pioneer"

In 1904, at the early age of 9, Alfred H. Grebe already had shown a strong interest in a new technology that would be "wireless". He would begin his tinkering at home which was on Van Wyck Boulevard in Richmond Hill, NY. The rest as they say is 'history'; radio-history that is. Select here for more on this ingenious man who hailed from Richmond Hill.

This design was heralded by many as the best unshielded tuned radio frequency "TRF" design ever made for the trade. The frequency tracking of the 1924 three dial model was sufficiently precise so that the dials of the1925 model were chained together to move as one unit. This was the first step toward the birth of the single knob tuned radio. Grebe's products were innovative and of high quality. He was representative of the radio pioneers of the day. He started from his tool shed at home located on Van Wyck Blvd, Richmond Hill in 1909 selling tuners and crystals sets to radio amateurs. After his return from W.W. I, his business expanded rapidly with high performance equipment. Unfortunately his skills shown in the quality of his products were not matched with skills in the business details. His company fell to bankruptcy in 1935.
