Yes, that is correct. The center tap and C101 negative should only connect to chassis through R100.
Thats why I said to measure the resistance from the center tap to ground. You should read 271 ohms, the resistance of R100.
If you do not read 271 ohms there is a problem. There must be 15 to 20 volts at the center tap to provide bias for the output tubes. This voltage is developed across R100 so if you have no voltage across R100, then the center tap is somehow bypassing R100 with some other path to ground.
