Default pick tubes for tubecad unbalancer

I have a dac based on a PCM1794 and uses 25ohm for the passive i/v conversion. So thats like 200mv (not sure if that means its 400mv when converted to SE). I wanted to try the new unbalancer but its out of my budget if i have to use $15 a pop tubes. Could i use the cheaper 6n6p if i just bypass the regulated heater supply? I know that a regulated supply meant for 200ma-300ma heaters is not going to like the 6n6p's.

They have a gain of 30 and im shooting for at least 1.4vrms output. Would this work or can you help me out with some cheaper pickins?
