[Hallicrafters] Black Beauty capacitors Beware

[Richard Knoppow]

       I am guessing a little here.  The caps are for mutual coupling to 
control the bandwidth of the transformer.  The curved line on the symbol 
and line at one end of the capacitor indicates the outside foil.  I 
suspect that the arrangement is to reduce coupling between the two 
capacitors. As far as connection to the B+ one is on the plate side of 
the transformer and the other on the side feeding the following grid.  
Maybe you are talking about something else here.  I mean the caps on the 
50 khz IF.
