Something very strange happened to me on stage last week and I wonder if anyone can shed any light on this..
For a bit of background, I have an Orange AD200B paired up with a 4x10 and 1x15 cab.
To DI this, I use a Radial JDI placed in-between my amp and 4x10 speaker.
The amp was also serviced with new output valves by Orange back in July this year.
Using the same cables and configuration I have done since I purchased the amp, I fired the rig up and played for 10 minutes or so during sound check. Everything was fine. As I took to the stage for my set however, it didn't sound 'right'. Second song the amp started farting like nothing I had ever heard before, and eventually completely cutting out. The DI signal also completely cut out, meaning It had to have been a complete amp failure.
Post gig I bought a cable tester as I thought maybe it could be something to do with the cables as they were the oldest thing in my rig. Having tested all of them, I discovered that one of my jack/speakon cable was wired the wrong way round. I.E Positive to negative and vice versa.
Could this have caused a problem with the amp confusing it perhaps?
Best,
Mike.
