Your schematic looks to have a 229V transformer with a choke input. If you look at your simulation, it shows 202V at C3, if I am not mistaken. Is C1 value as shown?
I use a similar arrangement with 220V transformer with choke input and I have around 190V before the regulator.
Are you sure?

Attached schematic how I wired the Lundhals LL1660, help will welcome?
I don't know if it matters, but I think you have the outputs the wrong way round on the LL1660. Plus should go to plus.
Why do you have a 100R between the transformer and the AZ1? Normally you want the lowest output impedance you can get.
To protect AZ1 maybe. But where do you see it?

An anodefollower inverts.
What is the last 2,7k/100nF for?

2K7 to low the voltage 100nF not used

What is the voltage drop on the 2,7K?
I have removed the CCS+Gyrator, I guess I need a dummy load in place of Gyrator and tube to measure, wich value?

If you have 306 something B+ you must have put something larger as the first cap then 100 nF. Check that, or remove it as earlyer said. Then you need a cap after the 2,7k. 100 uF:is I would say worx.
1rst 100nF removed, I don't have 100uF I have 220uF could I use after the 2K7?

for 300 V 5 mA 60k
for 250 V 5 mA 50k
for 200 V 5 mA 40k
for 150 V 5 mA 30k

Yes you can.
