This schematic by McKay is represented to be Tesla's original patent which simply has an HV source charging a capacitor across a spark gap into the electromagnet coils:

Gray's charging the run battery by discharging to the battery "split" positive with the increased voltage differential eliminates a need for a loop switch.

Any advantage Gray's triode tube adds is on top of these two principles: One discharging a HV DC cap pulse through the coil; Two, into the positive of the run battery.

Gray's tube may be just a "Fantazaler".
