I appreciate the information provided.
In TUT 2 it calculates the current using
Ik=Pa/(2XV+).
Using the formula for example on another fixed bias build with two power tubes let's say with el34s.
Ik=25W/(2X442V)
Pa = power rating of the tube
Which would give me 28.28mA
As I read in TUT 2 this is the reccomended value per tube which I usually bias at. It states biasing lower or higher is not recommended due to tube life and sound in factor.
In the datasheet it says for an el34 100mA. This is the maximum current? Although the datasheet might not be accurate for the actual tube on hand technically you should be able to set the current to 100mA per tube max?
