Ampeg VT-40 Screen Grid Question

[Jack1962]

On the schematic it shows C302b(filter cap for the screens) to be connected to C207(a filter cap for the Bias circuit) . Would it not be a better to connect the  negative lead of C302b to ground?

It's just drawn funny, but it is connected to ground (actually thru the STBY switch and a diode). Stare at it for a while and you'll see that it connects directly to the negative side of the bridge and the CT of the HT winding for the screen supply.
