I wouldn't think inductance would be an issue in a DC circuit such as a bias adjust.
That being said, I don't usually see any wirewound pots in the high Ohm values needed for a bias circuit. They are usually 1000 Ohms or less, and also they have higher wattage ratings than a bias pot requires.

Hi Al, here is an ad on eboy for some high value ww pots.

I was considering trying some for my project. cheers, Dak
Those look pretty good. Ten turns would be a bit of an inconvenience, though, unless you incorporate some kind of dial with a turns counter.
Yeah, i was wondering about that. I never used one of those type of multiturn precision pots. And actually, i decided against that one and stick with the 2w carbon element pot. Cheers, Dak
Think this will work fine. As one really shouldn't be tweaking the bias pot that much. A few times, during new tube break-in. Then, whenever you change tubes.
High quality wire-wounds I'd trust, look at Bournes 3543, 3445 and 3547.
