Eugene:

     I followed Breck's idea for arranging the stacks of batteries in my own PRC-6's with one exception.  Instead of forming a lot of aluminum, I simply used masking tape to hold the ten 9-Volt batteries together in one bunch and the C-batt holders in another bunch.  The 7-pin connector is attached loosely at the ends of the batt wires (don't' forget to use heat-shrink tubing around each socket pin).  This collection rattles around a bit inside, but you're not really using them in combat.  

     When I install the batteries for this set, I lay them out with the C-cells (in holders) and AAA-cells (in one three-batt holder) on the bottom of the case and the 9-Volt batts on top of these, just as Breck shows on his web pages.  When the batts discharge, I simply replace the C-cells in their holders and tape up a new set of 9 Volt batts.  

     As someone else here said earlier, the engineering and manufacturing that went into these early HTs, including the BC-611, is worth having and getting to understand.  It always amazes me how clever our grandfathers and fathers were in their use of bearskins-and-stone-knives technolgies.

P.S.  For another enlightening look at pencil tubes (used in the -6) check out the VT Fuze project from WWII.  You might want to google VT, Deke Parsons and Applied Physics Lab.

  I prefer usually for the "smaller" field set to 
  use home brew battery boxes. Battery power is very 
  quite and very reliable. Dollar store batteries 
  are my favorite but be sure and test them under at 
  least a 25 ma load for a short(2 or 3 seconds) 
  period.
