i just got one of these. did you ever find anymore info??
What it really is is the nsm counselette(wall mount console) and the lower part is the "guts" if you will the mechanics.. But on the sound master they just put it all togther to make this weird upright compact juke. I kinda like it. Doesent take up too much space.
well mine had two blown fuses. Upon replacing them the display came back up, carrige went full right, stopped. About a minuite later smoke came out from the mainboard and the display is off again. SO much for this being an easy one..
