A little help if you please. Looking at the schematic of the Philco 42-PT-7, #9 is the oscillator transformer, what is the unmarked capacitor also indicated by #9? And, is the connection point above the unmarked cap pin #1 on the osc transformer? And to return to my original chassis ground question; looking at for example #5 the 1.5 pf capacitor; where should its physical connection to ground be made? Is the ground connection symbol a shorthand indicator for B- or what? I understand that the little three line ground symbol indicates that all are tied together but how is the mechanical connection made? Where is it made if not to the B- common ground?
