@Albert: I ran the sawtooth signal through both Timebase A and B. There is still nothing on Timebase A. On Timebase B, it shows up nice and clear (albeit still on half the screen). However, when I change the time division on Timebase A, the sawtooth signal gets very badly distorted, sometimes to the point where it stays distorted.

I took out the CRT out of its socket to see if there were any bad connections and whatnot. I also looked at the CRT circuit to see if there was anything going on there. Everything seemed to check out. Looking at the circuit diagram in the manual, it seems there is a very high number of oil paper caps in the CRT circuit. Perhaps one or multiple are dead and need replacing?
