Yes this is one of those questions asked about few hundred times here.
The connection is counter-intuitive, as people are accustomed to seeing GND being the most negative point and so caps' minusses going to it.
In this case which is present in many radios, the centertap is the most negative point in the whole of the schematic; everything else relative to it is positive.
Hence the capacitor's minus goes to the centertap, and the plus goes to the Ground (chassis).

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
