Wayne is right. What I mean by deep is higher standing current. How much will depend on your speakers and how much power you need.
In my case I have a pair of Bottlehead Straight 8’s, at 96-97 dB efficient, so 1 or 2 Watts goes a long way. I don’t need to run the current very high to stay in class A.
As a rule start with low current and gradually increase it till you are happy. If you are after Max power again run as low as sounds good. The more current the more the 2 tubes overlap (more class A less overall Power) . Plus more current = more heat and less tube life…John
