Thanks very much.
You can give me diagram for it? I have Fe 32, but I don't find this in list.
ex: I want OPT is:

Zin=3100 Ohm
Zout=8 Ohm.
Consequently: Sec turn? Pri turn? and turn in sesion.

Hi,

Your iron size is very close to the "european" EI96B.

You could start this way.

Thanks very much. If I want change values Zin to 3100 Ohm then power is decrease. But I can use for 6C4C or 6L6 in the future, It's correct?
