Well the grid bonding straps are not just hooked to the socket screws.  If 
you know the underside of the TL-922, there are screws with long pins on the 
ends,
that are screwed through the chassis. The copper straps are also soldered to 
these screws/pins too. Look at the bypass caps on the filament choke. They 
are also soldered to these screws/pins.
