This fellow here works on many post war West German radios of the 1950s and 60s https://odysee.com/@ElectronicsOldandNew:c he has a backlog of restoration series posted on odysee, which is a much better site to view them on then Y.T, much fewer commercials. Most Saba sets have a name, I have no idea what a Saba 300 or 400 is but their top model used to be the "Freiberg" among the table models. West German sets have a lot of weak points, the main one being the fact that they use the band switch assembly to turn the power on and off which is also a dirt trap, and that actions wears them out faster. Most models are also sort of average in terms of AM performance, middle of the road on FM too, without extra IF stages, or a tuned RF stage, much of the focus seems to me in the tone correction/compensation in the audio stages.
