I couldn't stand it.. (Typical..... :-) )
The resistor (R143) is the 1.5k, 1W resistor added to accommodate the
2.5k coil relay that replaced the failure prone 15k coil version.
The capacitor (C194) is inside the PTO. C132 was changed from 90 pF to
45 pF and C194 was an added 45 pF, all indicated as NP0. Also inside
the PTO, C133 was changed from 12 pF to 10 pF.
So as I said, other values may have changed slightly, but only one
resistor and one capacitor were added. It's also possible that one or
more were deleted, but that would require a stage by stage comparison of
the two schematics.

Hello Drake pros!
I have a question I am just curious about.
My T4XC SN is 26595. Although it's a later SN batch, it's not in the
group of the very latest run built. What were the last Drake
production changes to this radio after this unit was built?
I found great info about my R4C by VE3EFJ but not for the T4XC. Maybe
there are details on the web somewhere that I didn't find.
