Hang on a sec. I’m pretty sure you should not ground any of the leads you are not using, including any center-taps that might be included with a specific transformer that are not called for in the circuit. Best to cut off or cap-off (or shrink tube) the end of each unused transformer lead.

The yellow leads are the 6.3v taps for the heater circuit (this transformer does not include a center-tap for the 6.3 taps so you must add an “artificial center-tap with 2 resistors).

The Green (#10) & Yellow/Green (#11) leads create the 5v supply for the rectifier tube. Cap off the 6.3 tap (#12)
