Hello, I am planning on just adding a 6107 tube to this, and just try using the voltage turned up to full at 500v. I want to add a resistor to the anode, but since the 6107 requires 1 meg ohm, rather than bypass R3 and R4, I want to use them, and add one more resistor inline before the tube to equal 1 meg ohm, so my question is, what is the value of resistors R3 and R4?
