BUONGIORNO!
Thanks for the good pictures.
Diodes & elythic caps were used to double the voltage before rectifiered.
This is a common practice in 100-125 Volts countries.
Means parts of South America, USA, France (parts of the county),
Spain (parts of the country) and it seems in very view local parts of Italy.
B.t.w., my vintage japanese TV sets have mostly 100 Volts/AC, only a few are able to run on 115 Volts/AC or so, too.
What about the languages?
Because of the appendix "/38" it seems to be a rare series with a very limited
production, because of the unusual voltages.
Do you know radios with the same unusual voltages? There has to be some in that same area!
Did you ask some italian radio collectors?
I have a nice collection of early italian TV sets (incl. 2 roundies), starting in 1952, they all run with 220 Volts/AC.

Just to bring back these sets to life, you have to paint a schematic of what you find in your set.
Its not the complete TV set (What a luck
) you have to "paint".
Your job will be simple, because it is only the power supply!
It is up to you, to run it with a special transformer you have to buy, or change
the set to the standard 220 Volts version.
But you have to decide with the historic view.
Good luck!
