Fine ! , I have designed a similar preamp years ago , with the ECC85 and the EF184 see the schematic there in post # 102 ... http://www.diyaudio.com/forums/tubes-valves/200823-my-new-circlotron-otl-tube-power-amp-11.html .

Yes, smth like this, but I will Take signal from the second tubes anode, to maintain absolute phase. One thing I don't understand: do I have to use negative voltage for ccs?
The easiest way to input models is simply to paste them into your schematic using the spice operation function and rename your symbol to the model name.

Yes , If you want to avoid any input capacitor , you have to use negative voltage for CCS .
