I read the whole thread and i must admit that damn, some of these are really horrid,

if i found a wasp nest or some kind of ant colony inside a boombox i´d leave it there and run far, far away from this
All i´ve found is few bug corpses, and in many cases dust from construction work as many construction workers and painters love using boomboxes at their work. I kinda hate it though, it´s a pain to clean

, my Hitachi 3D7 used to be construction workers boombox but was badly mutilated and neglected and whole inside was full of this mess. Sadly i didn´t take any photos. This dust appeared to be a mixture of plaster/cement, i don´t know but there were signs of it everywhere. Now it looks much better, although with some scars.
