I use similar bins as well. I have a cabinet with bins for 2879 and similar amps with all the repair parts in them and labeled. I also have a cabinet for the Ameritron tube amp parts as well as a bin for their solid state amps. Another cabinet for all the popular range of caps and resistors for generic whatever repairs. Then the unpopular stuff is just in a box under the bench with them put in zipper bags from such range to such range.
