Back in the late 80's I sold an AL-1200 to a well known FM5 where the power 
level was 200W and duty was high.

I UPSed it to Air France in Miami and the paper work indicated "Active 
Antenna Tuner" with a $400 value. The tube was sent earlier as a replacement 
at $100.

It all went thru without a hitch.
