I only work on 1940s British radios but I know that the Orion AR612 from Hungary is a popular radio. The Orion AR612 vintage valve radio was manufactured in circa 1960. The radio covers long, medium and short wave plus VHF FM. The radio utilises push button piano keys which can be problematic. It has a decent size speaker which gives good sound quality.
Sorry, due to lack of spares, this is a model I no longer repair.
