Capacitance itself almost does not matter, not for killing the generator.
What matters is the working voltage. If you used a small WV cap and it was destroyed, then it could've taken out something behind it.
Your gen probably has a potentiometer - attenuator, whose wiper then somehow is connected to the output. The pot could've died if the cap shorted.
Start with 1) turning the gen off and DISCONNECTING it from the mains, 2) take an ohmmmeter and see (if you have the sch) if your pot is OK or not. 3) The pot in its turn may be connected through another cap to a, say, cathode follower. See all elements there - the load resistor, that may go from the cathode to GND, the cap. I somehow think the extent of the damage is not likely to go beyond the output buffer stage.
