Yamaha DTXpress/DTXplorer/DTXtreme

John, with the sound of your description with the smell of 
electronics it sounds like a filter capacitor has failed. to find 
which one is easy sometimes and a nightmare the other that is the 
reason most power supply boards are removable. A computer is the same 
way the only thing about it is I hope it did not have a current surge 
and take out anything else. The bass hum you hear was most likely a 
AC hum. Capacitors filter the ac ripples from the dc voltage after it 
leaves the diode rectifier bridge. I live in the states and our power 
grid is 60Hz which is 120 volts. everyone else in the world is on 50 
220V. the transformers are switching taking a section of the 
transformer to get it down to a workable voltage. (here 120V) The 
advantage to the 50Hz is less current draw and appliances are more 
economical I hope they can fix you up and get you back. We did not 
have any glitches this weekend. our drummer ran his DTXpress II thru 
our system. I ran a Behringer FBQ3102 graphic EQ thru the main 
inserts to help with the bad acoustic where we were at. I play piano, 
bass and I play the drums some. I love the drums it is just you can't 
play everything at once. but being a bass player I know the drummer 
is my best friend when it comes to the rhythm section. I played a lot 
of Jazz when I was younger I learned then if the bass and drums are 
not comunicating the rest of the band is in for a long night.
