Thank you Tom
First, we have sound. The contact of the speaker wires are dirty, tomorrow I clean it but I have put a 12 ohm speaker for testing and seems to work. No snow effect, but the vertical slowly opened...
That UHF converter box are used also in Italy, but much people preferred put it into the set. The set in your photo it's a Zenith? Cool! And I love your Porthole!!
Maybe one day I open a blog with my TVs
