Eric, the treble control is a fairly simple circuit, only 3 parts in it. The control, a .01 cap and a 220pf cap. Looks like perhaps a shielded cable from the high side of the pot to the .01. Does it squeal when you touch the bare shaft or when you adjust it? Check the resistance to ground from the center tap and from the low end. Also did you change out the .01 cap?
