REASON
During production the chopper transformer has been changed from a Diemen
to Orega type.
to Orega type.
ACTION
If the original Diemen chopper transformer is to be fitted, follow the
instructions below.
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.
