My 42 is a Philco, which I did not see on the tube check but I used the RCA-42 as a point of reference. H & H both 0, k G3 = 0, G1=2.5, G2=323, P=323. The RCA 75 is H&H both = -.002, K=0, Pd1= -1.676, Pd2= -1.68, Pt= 254. I know from other messages these readings are out of line but that's what I have. Rich
