The model 79-A (manufactured 19??) apparantly came in an AC version only.  It uses the same chassis as Models 69 and 89. The 79-A is an 8 tube radio.  This is the least amount of tubes found in any Equasonne.  It uses a single 585 power output tube rather than the usual paired arrangement of two tubes in push-pull. The RF Amplifier unit is the same as that found in the 930, which differs very slightly from the 931 type, common to most models.   The tuning selector unit is also of the 930 type.  Models 69, and 89 differ from the 79-A.  These models did not come with a built in speaker.  Rather they featured a speaker jack for connection to an external speaker.
