Thank you for the detailed response.
I checked my connection again based on the schematic and your suggestions.
I am attaching photos of my connections so hopefully you can see if anything looks wrong. 
I also just tried moving 21A negative from Pin 2 of 77 to chassis ground.  No luck.  I still have the loud hum.
I will check the voltage next.  

It's important to note that I did not get the hum until the Bakelite #81 capacitors were changed to safety capacitors and the Electrolytic can #21 were changed.
The radio works but the hum is over powering.

Let me know your thoughts.

Thanks!

Todd
