Looks good. 136V on plate, 9.59V on cathode is basically the same working point as per Andy's schem (138 and 10).
Yea but where does 29 mA current go?

137V plate
0V across grid stopper
9,86V cathode positive to ground
Exact values for both channels? So what voltage do you now have over each 4k75?

Right channel
137V plate
0V across grid stopper
9,86V cathode positive to ground
over 4k75 64,4V
Left
125V plate
0V across grid stopper
9,47V cathode positive to ground
over 4k75 73,4V

Iko I don't have connected the 100R before the OPT, do you want that I connect to see if the voltage drop is 0,5-01V? also I don't have connect the 100nF input cap, is necessary?
It helps you measure/monitor the current through the tube very easily. While you're debugging your project, I recommend that you do it, just to make sure you have the right bias on the tube.

OK I will do

now you can read it

Right channel
Across 100R 1,372V
Left channel
Across 100R 1,544V
What's the voltage on the grid, with respect to ground? Should be 0V.
Left channel
+0,442V
Right channel
+0,448V
