How to replace a combined dry battery by an arrangement of batteries is described in:

Ghirardi, A.: Receiver Troubleshooting and Repair, Rinehart, 1952

272 - RECEIVER TROUBLESHOOTING AND REPAIR    [CHAP. 8

8-8. Battery Arrangements in Dry-Battery-Powered Receivers

Two main types of physical arrangements are used for the storage of batteries in standard-portable receivers: a combination "A-B" pack, and separate B and A batteries. The battery pack is designed for compactness and convenience of handling. However, since the A and B batteries do not become discharged at the same rate, it often becomes wasteful to discard a complete pack because one part of it is discharged. For this reason, it is desirable in many cases to convert receivers from pack operation to separate-battery operation.


Figure 8-13 shows battery-pack and separate battery arrangements and how the conversion is made by adding a battery-connecting harness which has a main plug for the battery receptacle on the receiver on one end and separate battery plugs on the other end for the two B batteries and the A battery. Standard harnesses for various uses are manufactured and can be obtained commercially; some of these are illustrated in Fig. 8-14.


Connections for a number of arrangements are illustrated in Fig. 8-15.


Plugs used at the battery end of the harness are illustrated in Fig. 8-16.


In personal-portable receivers, the B supply is usually a 67½-v miniature-type battery, which requires the cap-type connectors as shown in lower right corner of Fig. 8-16.
