Admiral 19A1, no vertical sweep (video attached)

Got any more 6SN7s and 6SL7s to try? how are the dc voltages in the vertical & horizontal circuits?

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)

Translation to Sams numbers

C36 = C46
C37 = C47
R42 = R81
R43 = R82
