Keyboard Amplifier Troubleshooting Question
February 11, 2014 2:11 PM Subscribe
I feel like if I knew more about amplifiers the symptoms of my Roland KC-550 would narrow down my problem significantly. Only the tweeter works (and it works fine), and the two other speakers are totally un-driven across all channels. Does this indicate anything about the issue? I'm trying to figure out if it's worth having repaired and/or if I can repair it myself.
