The first clip is from Leftfield and the box can be seen at

1:35 - 1:38 !

The second is from Daft Punk and the box can be seen from 0:34 -0:35

and then again at 2:31 and it seems like its missing the cassette player keys.

The last one is from Eric Prydz, the box is seen from 0:01 - 0:05

if you can focus on it and not on something else!!!!

and i think its a Unisef SZ-5000!

- the first one is Sharp GF-990,

- and the second one is Sanyo M9902 (M9909)

The mics,  tunnig knob and the carrying handle, and only one toggle switch on the left part of the top panel (at 2:01) .

And finally the pic of the top panel just proves -

on the right: 1 toggle switch, 3 sliders and "Variable sound Monitoring System" above the missing casstte buttons.

having seen the third clip i have come to the conclusion that the third unit is an ITT-bu-0X anagram -- a rare top model & a must in everybody's collection

Ofcourse metad once again with the right answers!

Anagram??? ITT-BU-OX?? I-O-BUTTOX
