Sparks Fly! Turbo controller is toast.

Not so surprisingly, the brains of this Turbo Controller are the same technology that help power the turbines in a jet engine. With that much packed into an 8x4 inch box, these controllers can eventually fail. This one was easily diagnosed because we were present when sparks flew and a puff of smoke billowed from the instrument. Our network of specialized individuals had a replacement part on standby for us, so this was a quick swap.
