In the key of C, A7+5 is common (leading to D or Dm) because the raised 5th occurs naturally in the C scale. Singers like melodies that lie within the natural scale, even if the chords include accidentals. In this example the raised 5th of the A chord is the F note.
A common spelling for steel guitar would be F C# G (high to low).
Here are some places to fing it on E13:
E -- 13
C# -- 12
G# -- 11
or
F# -- 11
D -- 11
G# -- 11
or on C6:
E -- 1 ----- 13
C -- 1 ----- 13
G -- 0 ----- 12
The same statements apply to the E7+5 chord in the same key of C, if you move all the notes 5 frets higher or 7 frets lower.
