Since both pins are ground, are we looking at a bad tube socket?

Not sure what M1 is. The pins and the ground trace on the circuit board should all measure zero ohms to chassis ground. VTVM or VOM will not make a difference - a ground pin or PC board trace should be a very low resistance short to chassis ground.
One more thought - make sure your ohmmeter reads a solid zero when you short the leads together.
