Let me try again




If you can see the changes I made to your schematic you will see that the 1.5k resistors are the voltage drop resistors and the 47uf caps are the decoupling caps and the 22k resistors are the plate resistors.

When you want to change the plate voltage you should change the value of the voltage drop resistors, not the value of the plate resistors.

I'm not sure what your note "B+ 2 supplied from terminal strip that has reduced B+" means.

The only thing that should be reducing the B+ is the drop resistors. That is to say, the full B+ voltage should be feeding each drop resistor and those drop resistors should be whatever value they need to be to give the voltage that you want feeding the plate resistors, and by extension, the plate voltage you want.
