All the Muntz sets, larger than 10" used a 5U4 rectifier.
The Hallicrafters 12" set, shown in a different thread used a 5V4. They built that same set for Sears as a 19" metal roundie. IIRC, that model used a 5U4, but all the smaller models still used a 5V4. The power transformer size was impressive, but seemed strange that they only used a 5V4.
