During manufacture, the CRT type fitted to the above models has been changed from
a Philips to an Orion type.

When replaceing the Philips CRT with an Orion type, carry out the following circuit
improvement.

1.  On the component side of the PWB, replace C601 with a 6.8nF, 1.5kV capacitor.
2.  On the component side of the PWB, replace C602 with a 820pF, 2kV capacitor.
3.  On the component sied of the PWB, replace C606 with a 330nF, 250V, 5%

capacitor.

4.  On the component side of the PWB, replace R609 with a 0.47R, 1W, 5% resistor.
5.  On the print side of the PWB, replace C607 with a 150pF, 50V SMD capacitor.

Please use the part numbers given below.

When changing an orion CRT for a Philips type, the original parts as per the service
manual must be used.
