Hi Keto:

The EXO-173 and 173PPS are each based on the original Peerless 17173 ct choke.

If you were to use our EXO's in a manner like that in the schematic you mention then you could allow a dc bias current... doing this by memory I think the spec is 100 mils.

But... and a big but... our EXO (especially w/ nickel) is not going to like very much imbalance at all... and, in advance, no spec was given in the Peerless folder on max unbal.

when our EXO's are used as a phase splitter and a 1:2 or 2:1 then we advise no dc current at all... since it is "single ended" primary... and no provision has been made to allow any dc unbal current.

hope I've said this well...
