Sounds like this one was hacked. No telling what else may be wrong, but if you can't get your money back :
The 7C6 is completely wrong for this set and will not perform well if at all. Completely different heater voltage and current. Get the correct tube. Don't have an extra 14B6. but would give it to you if I did.
Chuck is right. Check antenna loop, should be 3.2 ohms per schematic, and external antenna lug should be grounded to chassis. It will hum terribly if there is no loop antenna.
If the pilot light works and there is adequate B+ I'd leave the rectifier alone.
Also look for evidence (or lack thereof) of filter and paper capacitors having been changed.
Let us know.
