You did not ground it, you connected it. Grounding only means connecting to GND (chassis).
Now, 470 Ohms is a bit too much, this is your negative bias for the 41's grid, and it will be about twice as negative, which might affect the output.
As for smoking, if it smoked for teh reason of too much current, 470 ohm will have to smoke almost twice as bad as the power dissipation at the same current is proportional to the resistance (I-squared * R).
Have you found out why it smoked?
What else, oter than the #19 1M resistor on one side and what the sch has on the other side (#23, 15m K of 75 tube and the vol pot) was connected to it?

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.
