Unfortunately, the life of amplifier power transistors and to a lesser
extent valves is based on the peak power. Most license conditions are also
based on peak power.
A power control based on average power is therefore, irrespective of any
technical merit, inappropriate. It is theoretically illegal in many
countries to use with a following amplifier as well as being likely to
result in damage to that PA.
This is why it is such a serious issue and why we keep banging on about it.
