Concentrate on the power supply first. Check the rectifier tube(s) for DC output. If none, check the transformer for secondary voltage (AC). If you do have sufficient DC output from the rectifier tube(s) then trace the voltage through each dropping resistor as the power supply branches out to the various stages. Most likely, one of the power resistors is open.
