The 720 was my first rig back in early '60's. It was a nice looking rig
and a good performer for many years. As others have mentioned it does
require an extenal plate modulator for phone operation. I still have its
other companiion piece, the Eico 735 VFO, acquired when I no longer had
to be crystal conrolled.
Oops. Meant 722 VFO (anyone want one)?
If you ever see the old "Andy Griffith Show" reruns, you will notice
that a 720 sits on the radio desk with a mike plugged into the key jack.
Never quite figured how that was supposed to keep Andy and Barney in
touch!

By using a carbon microphone, of course! 
Cathode modulation, of course.
