in place of usual intermission tape<br />
player.<br />
Operates on 9 V. DC supplied by Dormeyer<br />
Charger shown at left or may be operated by a 9<br />
V. battery. Proper volume at speaker post is a<br />
smooth clean humming signal which should be the<br />
same at all posts. Defective speakers will rattle,<br />
sound distorted or be low in volume. Shorts in field<br />
wiring can be quickly located with "The Hummer."<br />
