dac output stage with 5687 pp

Hi all,

I wish to build a DAC output stage with a Push Pull of 5687 for my Dac Ah.
I have an input transformer elevator (audio tekne) and a pair of Tamura a-8713 (20k pp-600ohm).
The 5687's are polarized at 170V@10 mA(grid at -8 V).
Unfortunately the line output transformer have a max DC at 10mA x2 that is the polarization current used.
Do anyone use these line output transformer ?
Any suggestion is welcome.

Thank you in advance.

Ciao.

Luca
