Thanks for your time, I hope everybody's treating you like a human being today!
The L1 Model II is magical, we bought to of them and had great success with our last large choir / band performance in December. We left the speakers to be used by the church we were partnering with at the time, and in late February one of the amps apparently died suddenly, doesn't output signal and LED shows clipping regardless of input. Yuck. 
How do I just replace the power stand? And quickly, we actually need them next Friday, haha, I've been utterly snowed this semester with other technical difficulties. Praying the speaker and B2 are okay. Thanks!
