With reference to the product Gradiente model STR-1250 it was added in the text by the administrators that this model probably has Japanese parts. This is not correct. Gradiente produced this model (and others that I'll upload) entirely.
What happens is that our hi-fi audio market followed Japanese standards mainly with regard to connections.

Philips unsuccessfully tried to impose the DIN standard, but had to surrender to the market imposition created by other local hi-fi audio manufacturers (Gradiente, Polyvox, Quasar, CCE, Spectro, Gavox, Greynolds, etc.) who adopted the Japanese standard for connections .

By the way, this is one of the main explanations why Philips took a long time to take off with its high-fidelity products. Its DIN fixtures did not connect with any other equipment sold here.
