Ahh I see now that there ( at least) three R7's on the schematic one on
HV Rectifier Stack X43-1290-01 and one on the Meter Shunt board
X54-1300-10 and one on the main chassis !
As a previous poster noted remove the tubes one at a time

R7 as in the resistor across D7? did you check to be sure D7 is
