You must have a CRT with these specifications: 1) Will fit 10 pin neck, not a 8 pin neck. 2) Measure the ohms of the vertical winding on the yoke (Green and Yellow Usually) (Red and Green are horizontal).
The measurements should be between 11 to 17 ohms (Low Impedance) or more than 37 ohms. (High Impedance). Horizontal deflection does not matter on this model. **There is no Warranty on this item due to the complexity of installing this product**
