200A loud buzz associated with stage lighting

Postby jtkeoughan on Wed May 11, 2011 8:13 am

I have a 200a whose amp has been recently rebuilt by VV. Here's a quick recap of the situation: Outdoor gig, sound check before sunset everything sounds great, take the stage at sunset and as stage lights fade in an extremely loud BUZZ comes in over the PA. Stage hands determine it's the Wurlitzer's power cord. We plugged it into several different outlets all associated with stage power which does not fix issue. Finally someone ran a 100' power cord from main building to my Wurlitzer and problem goes away. Definately associated with light faders on stage, but only with my piano. No one else on stage had issue. Any ideas to keep this from happening again?
