was just checking others that i could find....... there are options but seems like Hammond is the cheapest (if i don't want to jump on Chinese chokes).... Thermionic Lab is more expensive, Toroidy i don't like, Lundahl and Sowter are waaaay to much... and so on 🙂
will probably go with Hammond 193C....

You can try :

SORRY this one :
https://fininamotaji.in.rs/Induktori_Cevnih_Ispravljaca-ICI.htm
Google translate to english although tabels are clear.
You would have to pay VAT & post, Serbia is non-Eu country so i don't know if this has cost benefits at Your end.
Local reputation is excepional.

Not all Hammond is made in China. The 193c choke is still made in Canada. So are the tube output transformers.
Look what i have found.... dc resistance is something around 150 ohms.... kill me if i know what inductance... havebto measure tue diameternor the wire tonsee if it will fit the bill for current....
If not, this can be removed and wound again...
I used this one on my ex 12B4A preamp 15-20 years ago....
Also i was searching in my "junk" boxes and found one valvo gz34 and two telefunken gz34
.. so gz34 it is.....

Found also some telefunken EZ12 but i believe the voltage drop across them would be higher then across GZ34.... and also new gz34 can be found so that is also covered....
Small drop and good current handling for a tube rectifier. Arcs easy though. Don’t do quick on-off-on
Hmmmm. I think i will keep those EZ12 in the box for something where i will not use HT regulator.
... those are fine sounding from what i know....
Here, GZ34 would probably be a better choice imho afterall....

2 time 7V/3A, 1 time 6.3V/2A and one time 5V/2A...... you are right - i completely forgot about that - will have to try 5VAC FIRST - before burning some resistors without reason !!... thank you
P.s..... on second thought - you almost got me 🙂 🙂 🙂 - GZ34 will be to much for my 5V/2A coil... i need to use 3A at least.... so it stays like on sch above.....
