IIRC, (I'm a little hazy on this) the sawtooth is produced by using the inductance of the deflection yoke and transformers. The output tube is turned on hard, and that starts an increasing current into the inductance, and that increases the magnetic field that deflected the electron beam inside the CRT. At some point (middle of the screen IIRC) the tube turns off, but the current in the inductance keeps going, so there's the damper diode that turns on. This pumps the energy from the inductance into a boosted B+, and keeps the magnetic field going.
