REASON
During production the chopper transformer has been changed from a Diemen
to Orega type.
ACTION
If the original Diemen chopper transformer is to be fitted, follow the
instructions below.
1.  Replace R608 with a 680R, 0.5W, 5% resistor.
2.  If a 18pF capacitor is connected between pins 14 and 15 of T601, remove it.
If the replacement Orega chopper transformer is to be fitted, then follow the
instructions given below.
1.  Replace R608 with a 680R, 0.5W, 5% resistor.
2.  Fit a 18pF ceramic capacitor between pins 14 and 15 of T601. 
Note that on the N2 version of this chassis a ceramic capacitor will have to be
used, in the N3 version of the chassis this is an SMD component marked C733.
Refer to the diagram on page 2 to identify the chassis version and location of
the 18pF capacitor.
Please use the components listed below.

Position of  Capacitor Fitted Between Pins 15 and 14 of T601
Note that The 18nF capacitor fitted between pins 14 and 15 of T601 is either an SMD component
with  the reference number C733 screen printed on the underside of the PWB, or it is a ceramic
capacitor fitted as shown in the diagram above.
