Hi,

Yes the tube still doesn't warm up.
The tube heater between pin 4 & 5 is around 10.3 ohms.

I just double checked all the components value, direction and solder joints of L1...L4, C37...C42, R39, R40, U6, Q1, D8.
I always get 15V Accross the 2 extreme pins of the tube PCB I
Any ideas ?
Thank you
