As some of you may know, I have use a Hiwatt valve head. I had a gig friday night, and after soundcheck I unplugged the head from the cabs, unplugged the power cord and wrapped it around the handle of the cab (i had 2 hours to go befor eI was on stage). I then went and got a pint and started chatting to people. I looked up at the stage half hour later and the lights were on on my head! my heart went into my mouth and I flew up to the stage and sure enough someone had plugged it in and turned it on, both power and standby, without any of the cabs attatched. Nobody seemed to have any idea of who done it, but thankfully the head is fine. I will not be leaving a power cord in sight next time! People are obviously stupid. Anyway kids, Dont give anyone an excuse to touch your valve heads! blown transformers are not good and I guess Im very lucky to still have my hiwatt intact.
