I wonder how many of these things Digikey sells to N scale modelers!

(And I'm really still VERY curious to see how Atlas does its speaker in the new sound-equipped GP38 and SD60's; fuel tank, I would guess, but Rick B has shown that it's possible to mount a speaker under the decoder if the frame is milled correctly. And that kind of speaker/enclosure would almost certainly give better sound).
