The last one I restored had the same problem it turned out to be a way out of spec plate resistor. The best way to check your resistors is to use a decade box if you have one this way you wouldnt have to unsolder the suspected resistor, the box resistor will bypass the bad one if the resistance has drifted way to high.
Hope this helps,
Todd
