Thanks a lot for your help, Anon. Just another question, as I'm really curious about this.

The cheap Chink radio from which I got the capacitor worked like shit. It had a selectivity so bad that a single station covered like half the entire MW band.

According to this article (https://www.petervis.com/electronics/tuning-capacitor/tuning-capacitor.html)), the ferrite antenna should be connected to the C4 and middle pins. However, on this radio, the ground cable of the ferrite antenna was connected to the C1 pin, which according to the article is reserved for the FM antenna (?).

Could this be the reason why this radio was so shitty? I can't believe that the Chinks that designed this radio made such an obvious mistake.
