Usually you have to pull the chassis out to get to the points you want to measure. Basically you attach the scope probe to a point in the circuit. There are a few spots that are accessible without pulling the chassis, it depends on the chassis. They did make tube test adapters that allowed you to connect to the tube terminals without accessing the bottom of the tube sockets but those are hard to find now and expensive when you do find them. I don't like the phrase "poke around" when dealing with high voltage tube circuits.
