Would a simple test be to put a VSWR bridge on the output of the radio, connect it to the antenna* and record the vswr.
Then put the amp between the bridge and the antenna and again measure the VSWR in the three states (On, Standby and Off). That should tell you pretty quickly if the amp goes into bypass when it is off.
*substitute a dummy load for the antenna if that is easier.
