The 185 and 245 ohm resistor are grounded at one end so if you ground the other it relieves any current flow thru it. So no wouldn't cause it to burn up. I would have a look around the 1st audio stage 39/44 tube as the cathode and screen voltage are developed at that string of resistors. Try removing the tube and see if you get the same results. Check for something that maybe shorting the socket at the screen or plate pins. Use an ohm meter to chassis ground. At the plate or screen should see something around 5k-10k and not 5-10 ohms.
