Fracarro 30 Line
(click on picture for high resolution image)
This set was made in Italy between 1929 and 1932. It is for the 30 line horizontal scanning standard used by Germany at the time. The condition of the set (it was supposedly found at a flea market in Italy) has made many collectors who have seen pictures question whether it might be an elaborate fake.
At the top the neon tube is mounted horizontally (because the aspect ratio is 4:3). On the shelf, from left to right, are the motor speed control, the motor and disk, and the syncronizing asembly, with connecting terminal strips in front of them. At the botom is a switch (probably not original) and a slide resistor for coarse motor speed.
The scanning disk is aluminum, with steel bolts and nuts attached. Synchronization is accomplished by these bolts and nuts passing through electromagnets (left side) on either side of the disk. This is similar to the method used by the Baird Televisor, which has a "phonic wheel" on the motor shaft with a set of teeth for each line which passes next to a pair of electromagnets.
The German standard was 4:3 aspect ratio, the same as the present U.S. system. Baird used a 3:7 ratio for his 30 line system, and used vertical scanning.
We have completed authenticating it. All of the experts we have talked to agree that it was made in the 1930s.
This is a closeup of the synchronizing assembly. The disk is visible on the right side, with one of the steel buttons.
These are the labels next to the input connectors
Fraccaro made this less elaborate receiver in 1930. It uses 30 line vertical scanning.
We have learned some more about the history of the Fracarro company. The following is from the Fracarro Radioindustrie website:
We hope to get more information about the history of this company. There is one discrepancy in this account. The book we have, titled La Televisione Per Tutti was published in 1930, and is from the G & B Fracarro Co. Note tbat the spelling of Fracarro is the "new" one, indicating that the company was formed in 1930 or earlier, not 1933.
It seems likely that the elaborate design of the cabinet was part of the Fracarro's attempt to market their television products.
