The rear of the core should be 1% from the mounting end of the coil form. (This measurement is readily made by inserting, a suitable plug in the mounting end of the coil form.) Core adjustment should be made with a non-metallic scrbw driver. *L is the pointer adjustment screw which is on the connecting link, between the pointer assembly and the parallel guide bar. It should be adjusted so that the dial pointer corresponds with the 1100 K.C. mark on the dial. With the radio installed and the car antenna plugged in adjust the antenna trimmer “G” for maximum volume with the radio tuned to a weak station between 600 - 1000 KC (see sticker on case.) 26 (For balance of circuit see diagram on page 23) 收音机爱 好者资料库 RadioFans.CN
