Typically a power amplifier is conditionally secure, where it will never oscillate so long as the supply and particularly the load impedances slide in just a particular array of appropriate values. It can be crucial never to electricity up a conditionally stable amplifier with an open up circuit, or it could oscillate and damage the amplifier.
