Application Notes
The tube/coil assembly consists of M38-200 tube and AT1991 deflection unit. To avoid deterioration of astigmatism correction, the coil must be at zero potential before being moved on the tube neck. Spot shift at screen centre should not exceed 1 cm if centring correction is applied.
