There are many different tools that you can or need to use at different times
to repair any item, tv car, vacuum. I have found most repairs were actually made
using observation, block diagrams, walking through what was happening in my
mind, using a voltage or ohm meter. Oscilloscope was not too often the first tool
I went to for a lot of troubleshooting.
While looking for examples of coupling capacitors on the internet I was not able to
find a good tube example, so I took that one from a tv. I did find a really really really
good page with some design stuff on it. Now you don't have to do any math to see
what it going on, and you can follow the examples pretty easily, just let it work in....

I believe this is a test page for someones website, so it may not be up too long....
I would download it and save it....
