The likely cause of your hum (based on your description) is heater to cathode leakage. If you have AC powered heaters the leakage can induce a hum in the tube.

Try running the tube for a few hours then let it cool and check it again. And be sure the base and pin area is VERY clean.

Go see if the GE you tossed out is retrievable too - it's definitely worth saving!
