Wow! I missed a lot. Holiday time does that.
Well...
1st...Yes, this is indeed a substitution only a knowledgeable tech would do. (AND this is great info to know as it confirms an optional way forward previously floated.)
2nd. This is normal. These selector switches were used in other Sansui amps too.
The X11 doesn't use those prongs / channel selector positions, but an 907 or a 607 might.
I have the same on my X11s.
3rd. Surprise indeed. There are supposed to be "black flags" on this driver board. (The drivers on my junk X11 has them and my good X11 as well.)
The tech who serviced that unit has saved you some time and effort.
He went in deep. (I wonder why?)
Leave the styrene caps in. They will live forever as long as you don't melt them.
Just make sure to clip heat shunts to their leads if you are doing any soldering around them.
Over all you are very lucky. I think recapping the unit has been made somewhat easier for you by the work done by the previous tech.
Still a lot to check and replace, but less than normally required I think.
Really, I think all you need is...

Really, I think all you need is...
- just a thorough cleaning of all switches, selectors, and potentiometers
- a replacement of all relays and trimpots
- a fresh application of thermal grease
- recapping (Kind of maybe? As long as you are in there?)
