Build a Cigar Box Battery Box for Tube Radios

Step 2 Installing the D-cell holder

For the A-Battery, heater batteries, I used a 4 cell D battery holder. Start by gluing the battery tray into the cigar box, I used some medium CA to glue it down, you can use what ever works for you. I decided to make the battery box more useful and tap the battery pack in the middle so that I could have either a 3volt A-battery or a 6volt A-battery. To do this simply solder a length of wire to the wire that connects the two rows of D-cells together and cut it long enough to reach the front of the box.
