In the schematic for chassis# 19A1,
There's four components in the H. osc circuit which, if they've been replaced and one were inadvertently the wrong value, could throw the frequency 'way off. They are: C36, .01 uf. comes off pin 6 of H. osc tube C37, .001 uf. connects between yel. and brn. leads of T4 R42, 39K goes to pin 5 of H. osc tube R43, 39K goes to pin 4 of H. osc tube (color code for 39K = orange-white-orange)
