I'm trying to understand this circuit. It is used in a tube amp for guitars. According to the full schematic the point "A" is connected to the plates of the output tubes and "B" is connected to the screens. Typically the screen voltage is lower than the plate voltage but in this case it seems to me that would be opposite.

If I understand this correctly then "A" should be 1/2 "B".

A and B voltage will be very close because the choke should have very low resistance, but it will have some and a small voltage drop across it, so B will be a little less than A.
