Have a look at the sounder options on the pcb nick and see if it has the "sweep" mode?,
If it has then run the sounder on this setting and have a jolly good laugh.
Sounds like a constipated cow :D
Ps mate the vision extreme is also tat but at least they have proper strobe tubes instead of the led strobe's like most now.
Think there's three 2watt xenon's on them been a while since I've had a play :),
We haven't had no probs with tex 3e's but each to their own but if we have takeover with one that faults it's straight out and up goes a quartz.
We not replace like for like :)
