Hello Kevin
thanks for your reply
It is not clear to me , i use unbalanced input on the primairy ( they call it assymetric , i guess ) On the secondairy I need 2 outputs
1 normal and 1 reverse ( 180 degree phase shifted ) so + and - normal and + and - phase shifted 180 degrees
Can you point out again which connections to be made ?
thanks in advance
If you want a very specific type of connection that is correct for your project rather than more general advice, you will need to provide a schematic of the circuit that the LL1540 is meant to feed.

hello Kevin
I use a tube preamp with low ouput impedance (300-400 ohm ) (unbalanced )
I want to use the schematic as shown in the picture or similar
What are the connections on the secondairy side of the LL1540 (pinnumbers (+/_) and 180 degr reverse (+/-)
Sent schematic by e-mail.

Hello Kevin,
It,s now all clear
many thanks for your reply .
Use the left diagram datasheet connections, but make the pin7-5 connection the center tap, pin 8 +phase and pin 6 -phase.
