Celsius, I think you do not take in your equation the input voltage. If you bias 6E5P with 4.1V then it can pass 4V with no feedback.  Since the tube has under normal circumstances 33 times gain then you have 132V RMS from your driver stage, wish is if I am not mistaken 373ppV.  That is all that 6E5P can do and among the tubes that I have seen that is one of the highest voltage swinging triode that still can handle 8W on plate. If you would like to use other tubes then it would certainly do but I can only comment upon the tubes that I know and tried.
