A-190 on fire.. hmmm

2004-03-20 by Mickey Finn

So I had just recently posted that I was having trouble with my 190. I had received it a 
month ago but finally got around to plugging a midi cable into it.. I could not get any 
gate/clock leds to light. It would select options (config/perform) with the correct led 
sequence, and even list the version number; but there was something 
wrong.. I opened her up and re checked the cables. I powered up and blew a fuse. I then 
replaced the fuse and powered up again and smoke started pouring from the 190.. I 
powered down and opened up the 190 and the Q1 transistor (bc549) had pretty much 
melted.. the rest of the system is fine, I just checked; so the power supply is okay.. Maybe 
this was a  faulty 190? I'll return it, or should I try replacing the Q1 transistor? Anybody 
else have this problem??
