Philco 89B headaches

Well, I took the coil out, baked it, checked resistances, and - no change. I took a look at voltages, and found I have about 200 volts on the plate, and about 126 volts on grid #2. Interesting, since the RCA tube data book shows 90 max for grid #2. Is there a voltage chart of what I should be seeing available? I re-tested my 36 tube, and I must have been mistaken, the emission test looks good.
