+ Found other possible speakers to use for project:
   - 1960's Calrad Alnico 12" speakers: I remember finding these
     for around $20 in a Salinas, CA (or about there) antique store



    


+ Reworked chassis for new application
   - Removed front hinged door and hardware
   - Cut off unnecessary threaded posts
   - Ground off spot welds and removed interior 

     braces/metal. Ground down residual metal posts.

        

+ Things to do (chassis)
   - Mount previously used front panel to "new" back of chassis
      + Clamp plate to chassis
      + Mark plate, through threaded holes in chassis
      + Drill holes in plate (size of screw to be used?)
      + Mount front panel plate to chassis with screws
   - Prepare amplifier control panel
      + Control panel will lay flat on the longer,
         narrow sides of the chassis (side with holes)
      + Dry-fit control panel
      + Determine spacer needed to lay flush with chassis
      + Determine where/how control panel will attach to chassis
      + Determine how many controls (knobs/switches) needed
         - Draw up plan in CadStd
         - Verify/double check
      + Drill holes for controls
   - Prepare chassis for transformers
   - Determine locations for circuit components; tubes, etc.
   - Determine how chassis will be installed into cabinet
