A couple of times during thunderstorms while listening to a Forte F44 remote controlled preamp I was in the room while the volume ramped up all the way by itself. I chalked it up to the lightning. Other times I'd return home and mysteriously find the volume on max. Sometimes the volume motor would lock into advance mode like it had a mind of its own. Unplugging the unit would reset it. To protect the system when not in use I learned to engage the mute relay. Convenience has its consequences.
