Hi Soliman15!
Thats a beauty, a real good find.
Congrats!
I have a collection of early swedish TVs and lots of swedish TV schematics, I check if I have it.
Mullard is the british Philips company.
Like Valvo is Philips-Germany.
This set is 100% swedish.
I am not sure, but I don´t remember much swedish tubes makers.
AGA made them.
Sweden is a big country with a small population.
They imported much from Germany, a few from Japan & England.
Philips was big, too.
Their own companies are AGA (Stockholm), Luxor (Motala), Radiola (has nothing to do with Philips-Radiola/France) and Prinsen (not sure: Malmö).
I own a 1958 Prinsen TV, but they are ultra-rare and there is nothing on the internet.
Sweden started like Finland and Spain in 1956 with CCIR-television. That means: No roundies and no 14"/70° sets!
Some companies in Sweden badged german TV sets with their name.
Mostly Körting, Nordmende and a few early AEG-Telefunken sets.
Regards,
TV-collector
