Evan,
Thanks for the suggestions! Went down that path first. Even tried tried switching what I though was VOl-Hi and Vol-M, no change. When you are saying "8kohms between high and ground" are you talking in circuit? My (cheap) pots are showing 10.5k.
The fact that the headphones which is driven by the same wiring doesn't show this problem is puzzling.?
