That is an ancient one. It may be a bad tube however you must have the 1500v and 90v on either end. It can also be filter cap(s) in power supply.
Focus pin#8 should change around 140~275V.
That will give you an idea. Check resistors in between the two voltages.
There is a detailed schematic here. Page 72 shows all the power supply outputs.
