The tube compliment is similar to my low B+ Emerson AC/DC set. MY set has the 14HP4, but the Sams states the set came through with a 14HP4, 17LP4 and a 21YP4. Somewhere in Riders it states that the 14" was the only one designated as AC/DC, even though the circuitry is similar.
It seems, the B+ wouldn't be high enough, running on 120 volt DC, to operate the larger CRTs.
