thanks manualblock.the tt is about 12 years old now but has worked fine until the move. I was careful as I possible could be when moving it and don't recall banging it. i did not move out of the country but I think I will consult some experts on this.
(i covered my bets and posted here too: http://www.audiotoolsdirect.com/cgi-bin/ubb/ultimatebb.cgi/topic/23/61.html?
i've contacted Noteworthy as they seem pretty useful and are local-ish to me.
thanks again.
btw - haven't come across any groups/fan sites for PT yet - you?
