No, Q6 has to do with feeding the LEDs only. When you will fix ''Wrong channel
C5 not connected to GND & R5 connected to R7'' there is chance 2nd and 3rd stage will work if nothing had burned. Leave Q6 change last after you review every tiny connection from in to out and voltages will be measured once more.
P.S. Did it ever get more than 45V during your shunts problems?
Anyway, Merlin The Wizard in the end can lift spell.

Seems that the dual njfet lsk389 is bourned, due to the fact after connecting C5 to GND & disconnect R5 from R7 I measured R7 to GND 0.68V & Drain Q5 to GND 10.50V. To change lsk389 I have two options: one lsk with 11.23 Idss + 11.29 Idss or other lsk with 9.74 Idss + 9.72 Idss, wich one could I use it?
Can't remember during shunt process if voltage exceeded 45V.
Yes, always I have the last chance in the end to lift spell.

Changing Q6 will increase the voltage between Drain Q5/GND to 21V?

First option.
After checked 4 times the connections I replaced the dual LSK389 (Q2 & Q5) for the new LSK389 & the voltages follows the same Drain Q5/GND 10,50V & R7/GND 0.68V.
I suspected about the resistors values for R9, R10 & R11 so I checked:
R9 100R4 instead 100R
R10 2K37 instead 2K4
R11 6K12 instead 6K2

I AM VERY VERY HAPPY.
Only was necessary to change Q6 now I have:
LEDs 7.33V (return original colour: after orange, now very nice yellow)
R17 347mV
R10/Q2 10.06V
R1/Q3 11.5V
R7/GND 10.21V
Drain Q5/GND 21.1V
Now I have only to wait a couple o day the new Tx from Mouser so finally I will hear the heaven
