Thanks Dave.  The ham with the question should now be able to
determine his 100B keying method.

In the instructions Heathkit states "...this strictly optional..."  It involves drilling a hole in the front panel to install a push button switch and installing a terminal strip on the chassis.  if there is no push button on the upper right side of the panel then the grid block optional modification is not installed.  A copy of the Heathkit instructions for the modification  is on Glenn Zook's (K9STH) web site.The Antique Radios forum is a wonderful resource. This modification has not been discussed there yet.
