I want this number as well. Almost bought 100 for .07 each until I reread the listing and saw they were 1 meg and not 1k.
I just had a unit on the bench which could not get the Bias below .420V. Found that it had 750 ohm ones installed. Maybe they really did get a little high at the factory.

Sure, Mouser 531-PT15B-5K They have stock on these. Not very good pots, but are much better than the original pots.

Thanks Joe. Are there better choices with the same pin spacing?

That is the best that is out there with that pin spacing Glen. It is not a bad pot, I prefer the cermet types but those all have the miniature footprints.
