Hello!
I do not know which is your location, but for me it was easier to find cores C-core Russian TV, very good cores, TC-40 TC-90, or TC-180...... So I recommend C-section core with at least 8 cm * 2.
But doing well and E + I with a minimum core section of 16cm * 2.
I am in China, should be no problem finding the core.
Thanks,
Jaz
With pleasure, have in the schematic drawing data for OT GU50 PP (triode mode), Raa = 3700ohmi (4000ohmi)
There are two variants: with core E + I-section of 18 cm * 2 and another on the core C-core section of 8-10cm * 2.
The coil design is the location but also their connection phase.
For a PP pentode will be recalculated for Raa = 5000ohmi.
I hope the drawing is understood.
If there are questions, answer with pleasure.
The transformer is made practical and works in multiple copies, project schematics and the OT is personal.
Excuse my English!
This information is excatly I'm looking for. In my case The Vp=700V (40W_max plate dissipation). Is 5k_ohms Ok for this voltage? I calcuated 12_kOhms, but I'm not shure. What do you think?
Thanks

In my case the tubes will work as pentode.
Thanks
