V4 cathode to ground.
stajo let me put new battery to DMM and I will do new measurements.

Felipe, much higher is expected. With your particular resistor values around 175V DC when normally working.
My fault: I measured from V4 cathode to output GND, now measured from V4 cathode GND to output GND from SSHV2, both channels start up 262V for few seconds. Also new battery🙂
That’s way out of safe zoon for 200 v speced caps. And a little worrying, means your V2 is conducting late. If you’re using 7n7, try switch them

Very near to simulator. So 25-30V below the 200V DC rated caps you consider. For the majority of time. But for very little time during power on it jumped 62V over. That's going to eventually kill such caps or it will degrade them depending on their surge capability. Unless the jump above 200V thing changes with tube swaps, certainly use 300V rated caps.
Yes mutually swap places of the 7N7s in case the other tube conducts faster during turn on. Also try more 7N7 if you got spares.
