Hi Raymond.
look like we are a pentode lover . your plate load on the EF37 seem to be in a very low side , I assume you run 2 stage SE ?
47k load will not give you much gain as you already aware of the low load on the pentode.
i think 82k is about the right load with around 300v in .
what is your screen grid resistor ?
i'm on my way designing the drive for my new 300b SE so i'm picking the right drive at the moment , too many choice here to thinking about,
Cheers
