if the resistors check out you will need to go back to where they connect up.

the 180k goes to B+400v check there with meter, then check where the 150k goes to ground should be 0v there, then check the junction, should be +180v there. has to be.

if you replaced the resistors you need to make sure you connected up to the correct location, esp the B+ side. During our talk IIRC you said it was connected to the output of the 1s diode of the doubler, that is NOT where the 400v is but more like where the 200v is. the 180k goes to where the 400v is.

if you have it hooked up right (180k to 400v) and the junction is still around 90v, it would mean you have a leak to ground somewhere, disconnect the wire at that junction and check the voltage at the junction of the two resistors again, if it pops up to 180v from the 90v then..

perhaps that .1+.022 cap. if this is the case try disconnecting the .1+.022 cap (lift the ground side) and check the voltage again.
