if possible take some close up pictures of the resistor in question that is burning I like to know what is the exact location of this resistor so I can know which anode resistor, and also the surrounding socket and connections.
In order for that resister to be burning, there has to be an incorrect connection, excess solder connection, or other variables like if you using tube adapter sockets.
The fact that your measurements are similar only shows that the PSU is feeding the resistors.
You need measure the Anode(plates) from chassis ground to each anode which ia the other end of the resistors.
Did you measure with tubes in place?
The burning resistor must be having a problem from the Anode connection or the bias for that specific triode section, or a wrong connection by that specific triode cathode connection.
We talking only three points for that specific triode (anode-grid-cathode)section of the circuit and socket area.
Coin is right an incorrect bias is a possibility meaning a wrong connection on its grid.
all other sections are fine don't start looking at the unit as a whole board with 4 powrtube sections , as you only have to focus in that one specific tube section.
