Hi there, Got an old set from a friend and it was working fine (my boys were loving it) then power in one track disappeared completely. I tried switching controllers round which showed wasn't a controller problem and also reversed the power base which showed it wasn't a track problem. So I'm guessing there is a problem with the power base. The wiring looks all soldered in still so I'm a bit lost. I guess I'll need a new power base, but I'm lost on ebay looking for the right one. I'm not sure I've got the right code/ref for the power base and there aren't many that look like the one I have. Andy advice? Thanks
