SOS folks.... I use a WT 800 and have been gigging regularly with it for several years. Its had its quirks but lately I have been experiencing the entire PA... Shutting down Losing power and moments later powering back up. At first I thought is was the venue's power circuit, Then it happened at another. Then another.... with this one being the House PA (Same power circuit as my amp.) That told me its not PA related. It seems to occur happens when I push my amp. ( Pedal, boost during hard rocking runs). I'm running the amp bridged into a 4ohm 410 XST. Everything on that circuit shuts down.... Lights, PA, Monitors, like the circuit breaker tripped and then it comes back on after a few seconds. My gut is telling me my amp is pulling the circuit down. Ive been playing these very same venues for years, Same gear, no change. Have any of you experienced this. Is my amp about to grenade? no burning smell or anything.
