Yes it is but not for GZ34 (i used thlransformer i wanted to make 6n1p cathode follower with so i had couple of different coils prepared just i ln case i decide to go for 6n6p or something like here).... 1.9A on a 2A coil i don't like (i don't trust that much in local guys who made that toroidal transformer.... better safe then sorry....
O.k.... i have checked what i have in my junk box of parts....
as said in my previous post, found some Riken, Takman and Shinkoh....
Please, can someone check ( @Salas also if possible) can i use these values with no issues - i don't feel these might be a problem but just checking.....
also - what you would like better to see as R1
Thank You and cheers

so to conclude for now - questions/changes needed to be confirmed are bellow:
1. should i leave the component values as is because i will probalby end up with my B+ in between 280 and 290VDC ?
2. what to use the best (sound/valuewize) for R1 - Riken 390R or 1k - or Shinkoh 330R (never used these so i really don't know)
3. i know now R2=200R is o.k.
4. resistors R4 and R5 can be whatever in between say 220k and 1M - i had 910k so i can use those imho
5. resistor R3 - it can be as R4/R5 more or less but happens i have 240k which should be good imho
6. tubes - try to get RCA 6V6GT os TungSol 6V6GT STR instead of russian ones i have at hand just to be safe....
right?

As Salas said each 6V6 draws about 15-20 mA and I thought that you need some margin for the regulator. Aslo if I remeber correctly I had seen some implementations around 23mA.
With your parts in hand and 285V B+, to DC center the circuit you got to use a 7.5K 10W power resistor or two 15K 5W in parallel.
Salas - you are the best.... thank you
So for R3 - would it be to wrong to try in between 1k and 330R.....
