Is this measurement with the 45 in or out?If the tube is out, measure again with the tube in.
If you still get ~ 0VDC at pins 1 and 4, then something is wrong with the tube. If you do NOT get ~ 0VDC at pin 3 (the grid) then your 470K grid resistor is not soldered correctly. Everything else looks good.
("~" = "about" - by ~ 0VDC I mean the type of numbers you are getting, less than half a volt.)
