[ARC5] Radios in XB-19?

[Jack Antonio]

Does anyone have any documentation on the radios installed
in the Douglas XB-19?

Note, this not a typo, I am not referring to the B-18 Bolo.

The XB-19 was the large experimental bomber that was used more
as a test bed for large aircraft systems, rather than a serious
contender for production.

What drives the question, is that one of the features of the plane
was the use of an AC power system.

So I'm wondering if the Army used AC powered radios in the plane.
