Tom,

You would install the tuner aid between your transceiver and your amp where 
the power is low.  Switch off your amp or set its controls so that your 
transceiver is connected to your tuner and antenna, adjust your tuner for 
the null in noise which is the lowest SWR.  Now you can turn on your amp and 
enjoy.  The tuner aid will never see the amps high power.  All you will need 
is an additional  short coax jumper to install the tuner aid.  Before using 
your amp you can test the SWR with the TW1 or the SWR meter on your 590 to 
insure it is within reasonable limits.

Remember, you should turn off the tuner aid before transmitting even though 
it has a protection circuit in case you forget.  I wouldn't rely on this 
circuit in place of turning it off consistently.
