W. MILLER COMPANY 5917 South Main Street One of the most common faults of the garden-variety small PM loudspeaker is a punctured cone. Since cost of recoiling such a speaker is almost as high as that of replacing the entire unit, service-shop junkboxes are usually fairly full of these units. If used normally, they produce strange and annoying rattles and squeaks. However, these speakers can be salvaged. Here's how If two or more speakers are mounted in the...

In case panel space does not permit two convenience outlets, as are used in the circuit o Fig1. 2, but it is still desired to provide one outlet at full line voltage plus another controlled by the Variac, some models of the dual outlets contain a removable link which will permit the isolation of the two circuits- The neutral and ground remains common to the two sections of the dual outlet.
