Tubes are in the wrong laces

Wow, I am sure glad that I posted a picture.
Yes, all the tubes are all in the wrong places and I would have never thought that the diagram was wrong. So now I can't trust the the schematics. I changed all the tubes around , according to the label underneath the cabinet and slowly turned the power back up with the variac and all the tubes light up.
Now I have a lot of hum, and if I just touch or tap the rectifier tube 35Z5 it almost sounds like I am taping a microphone. If I just tap it, the hum is louder and then just press on the tube, the hum gets a bit softer again.
The whole radio is recapped except two of the molded caps and I have not check the wiring to the schematic to see if it is all that it should be. I recapped the radio exactly to each capacitor what was in the radio, one by one, so I did not make a mistake unless it was wrong before.
I am getting zero radio reception and I may just try some other tubes from my stash.
