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 .

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.I think I'll go for LTP with BJT current sink, and cathode follower with resistor load (maybe change it for active later). Global feedback. Right now I'm struggling with getting tube models into spice.

One thing I don't understand: do I have to use negative voltage for ccs?
Yes , If you want to avoid any input capacitor , you have to use negative voltage for CCS .
