Show Removing Transformers From One Set to Another This article Is a description of a method whereby the formerly immovable immov-able A. F. transformers in a receiving set can be moved from one set to another an-other as quickly as a vacuum tube and without disturbing any wiring or loosening and tightening any nuts or binding pons. This arrangement makes the purchase of more than two or three transformers unnecessary, no Bus Hire-. A,, v-v.

Transformers for Test. matter how many different receiving sets the expermenter may use. : The scheme, as can be seen from 1 the drawing consists of mounting the , transformers upon separate, identical j bases of bakelite or formica on which j four contacts made from switch stop pins are fastened. The contacts are I wired to the terminals of the trans-i trans-i formers. If different makes of trans-' trans-' formers are used, be sure the G P B-j- and F terminals are wired to corresponding cor-responding contacts on the bases to prevent reversed connections as the transformers are moved from socket to socket. The sockets consist of pieces of formica or bakelite cut slightly larger than the transformer bases. On each of these are fastened four binding posts and four "Rasco Sockettes" (small size). If the "Sockettes" cannot can-not be obtained, cord tip jacks which will accommodate stop pins or the arrangement ar-rangement shown in Fig. 2 may be used. To avoid placing the transformers In the sockets Incorrectly, do not arrange the contacts in a square or rectangular formation, but place the primary contacts con-tacts closer together than the secondary sec-ondary contacts. , This idea is also useful In making comparative tests between different transformers, and also the best position posi-tion in the circuit for different radio transformers. |
