I am replacing electrolytic on my collection of Philco T7's, and noticing considerable difference in the layout and electrolytic values- the 124 & 126 use 3ea 100uF, but the 128 uses one 100, one 20uF and a third that looks like just a Philco PN with W.V. but no uF marking, does anyone have a correct schematic for a T7-128 by chance or the correct value for the third cap?           [attachment=20999]
