+ 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
