Early 50's set, Is this missing the deflection yoke?

Also, the larger screen sets, where the B+ demands were higher.

I know that two 5U4 tube rectifiers represent a four diode smoothing of the AC waveform. I wonder if the old sets more commonly used plain full wave, full wave bridge, or perhaps even doublers. Maybe a little of all of them. Just curious.

You'd have to look at the schematic to see how they're connected. Sometimes in parallel, or each one connected, half wave. They also used two rectifiers using two high voltage windings to obtain two different voltage sources.
