I cleaned out the HV cage last night and replaced the missing 1B3 rectifier. The transformer inside the cage is just for the 6W4 damper tube filament.
Then, I took a closer look underneath. The are a few deviations from the Sams but overall it matches well.
One thing that struck me though is the crazy assortment of resistor types. Lots of 30s style dogbones, some from West Germany, some odd body styles. Also some series and parallel combinations to get the right value.
This set is from around 1951 so I'm guessing it's a result of parts shortages from the Korean war and spike in TV demand.
