Your circuit has nothing to do with the actual amplifier. The load is not the same and the 6H8C is poor for that application. The 6H8C is only good for less demanding applications. There is no evidence. As I said you are eating an apple and conclude that that the carrots are not good.

But it is not class A2. Nothing bad about it. I have said many times class A2 is not necessary with 300B being already a tube with good efficiency. But class A2 can give a bit more performance in all aspects if it is done right!
