There are two types. The one I am missing are the two rectifier filter caps, and they are clamp-held, from which I surmise they were two-terminal type.
The other is still in place and it is a screw type with 4 wires coming out, as it contains 3 caps inside, with the common negative referenced to B-.
Interesting thing is that although it does not look like an insulated type it in fact is as though the can is in contact with the chassis (and it is a screw type), the chassis itself is not connected to either of the power nodes. That is the chassis is not really "hot". It is connected to the negative via 0.2uF cap and serves as RF part's common, I think.
