Seems to me the capacitor in question was added in parallel with the cap between the driver's collector circuit and the final's base circuit. Seems to me the magic capacitance value was 68pf. We ended up with thousands of ceramic disc caps that value after buying out parts inventories from closed shops.
Basically served to boost the RF drive level to the final transistor. Only helps if the final is capable of the additional output.
