EverReady #467 Battery Substitute
For Portable Tube Radio Sets
March 2012
Many portable tube radio sets were designed to use a 67½ Volt “B”
battery. In this paper I will describe how I made a nice-looking
substitute battery for the #467 type, using seven low-cost 9-volt
transistor radio batteries. My total cost for seven “heavy duty” 9-volt
batteries from BigLots was $3.33 plus tax ($1.90 per 4-pack).
I found a paper on internet, “A novel 63 Volt Battery for Tube Portable
Radios”, by H. Kristian Walter, dated November 1, 2004. He showed how to
arrange the seven 9-volt batteries to fit within the envelope of the
#467;
I followed his approach except for the enclosure. I need for my
enclosure to provide the beveled edges like the original #467, so that
the replica will fit properly in my Olympic #449 set and possibly other
sets.
I made parts using cereal box cardboard, sharp scissors, and Elmer’s
glue. I used new snap connectors from BatteryCentralMall.com. The
backing board for the snap connectors is just two layers of cereal box
cardboard glued together. It is surprisingly stiff and approximates the
original connector. I used Scotch “Gloss Finish” transparent tape to
fasten batteries and parts together. My completed battery assembly is
shown below prior to applying the inner paper wrap.
Cardboard Parts (use Elmer’s glue to stack pieces);
1 Side Spacer Type A; A1 2 pieces @ 7/8 x 3 3/8
A2 7 pieces @ 7/8 x 1¼,
A3 4 pieces @ 1 5/16 x 1¼
1 Side Spacer Type B 9 pieces @ 7/8 x 1¼
1 Bottom Cover 1 piece @ 1 5/16 x 2¾
1 Snap Connector 2 pieces @ 1 5/16 x 2¾
1 Middle Insulator 3 pieces @ 1 5/16 x 2¾ *
2 Battery Shims 6 pieces @ ½ x 1 ¾, (each)
1 Top Shim 9 pieces @ 1 5/16 x 2 **
* make cutout to pass wiring
**use more or fewer as necessary to fit and provide support for Top Cover
I used quadrille lined paper for the inner wrap. The Type A spacer is on
the side closest to positive terminal.
Here are drawings for the cardboard parts. The positive terminal is
located on the right side of the snap connector template, as viewed from
top of battery (see also the photographs of original battery).

Mr. Walter made a nice replica label that I printed and used.
