> Do you want to put the protection inside the power supply? That brings up a question in my mind. Is the actual cause of damage to the finals the failure of the bias circuit, or is it due to the finals being overdriven? In that case wouldn't a device in the power supply which limits the power supplied to the rig to a safe level be a better idea, or an "overdrive" cut out? For example, in a transitor rig there is often some sort of protective circuit to prevent the finals from being destroyed if they draw too much current. Many Japanese rigs use limiters o "fold back" circuits. Ten-Tec does not use one, instead they includea saftey cut out in their power supplies. Could a similar circuit be devised and used in this case? Geoff. -- Geoffrey S.
