No idea if there's a width adjustment.

FYI

In sets where the convergence is adjusted partly by tilting the yoke (which also affects centering), and there is no width adjustment, the set would be designed with extra width, so moving the yoke would never produce black edges. Also, solid state sets were often designed with wide retrace pulses to reduce the peak voltage on the horizontal output, another thing cutting off the sides, compensated by the extra-wide horizontal sweep. (Easier for transistor horizontal output stages to produce extra current rather than extra voltage)
