Default K12M / K12G Current Draw

What is the expected AC line current draw of a K12G? I'm getting ~0.7A after warmup, and no variation with or without drive. Thanks!

That sounds a trifle high to me. About 32 watts for B+, 20 watts for heaters, power factor of 0.85 gives 61 VA or 0.5A at 120V. Of course that's a precise calculation based on three SWAGs... (stupid wild a** guesses...)
