Ernie,
There is SO much on the 169, but see if this helps:

RCA CTC169
Chopper shorts. Replace chopper and regulator ICs, fails soon after
When Q4101 (chopper) fails it takes U4101 with it. Also replace C4108
(208002), C4102 (195691) and CR4122 (200158)
---------------------------------------------------------------
RCA CTC169
Chopper Output Runs Very Hot
Simpson'S Tv
After Replacing Q4101 Ecg 2311,& C4112 .0056/800v, Set Come On, But Chop
Output Run Very Hot, Cr 4122 Shorted 200158,Ecg 5065a,C4110 470 Pf 1500v
Was Bad
---------------------------------------------------------------
Also, always a good idea to replace C4118/190496 (470@35v) &
CR4118/164590.
