It amazes me that an amateur radio amplifier manufacturer would offer
an amplifier that had no standby switch or setting.  I wonder if that
amplifier that you mentioned bypasses when the power to the amp is
off?  Does it use RF sensing to switch the relay(s) or does it use a
control line from the rig?

Unbelievable!
