Philco 90
#2

The #9 shorting should not do anything to the coils unless instead what you think you did you shorted the top (as shown in the sch) part of the cap to the GND; then that could burn the primary.
The secondary could've been open on its own.

I advise you to inspect all the coils, every single one, for oxidation, green spots etc. Even if they do not test open, that warrants rewinding them.

As for the tube contact, there could also be intermittent contact inside the tube's pin. Not necessarily in the panel.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
