ELECTROSTATICALLY SENSATIVE DEVICES

Many solid-state devices (especially Integrated Circuits) are
Electrostatically Sensitive, and, therefore, require special handling
techniques as described under “Servicing Electrostatically

Sensitive Devices,” on page

two in this service literature.

4. PARTS MARKED WITH ARE RELATED WITH X-RADIATION.

NOTES;

1. RESISTORS SPECIFIED WITH RESISTANCE VALUE ARE "1/6DJ".
2. RESISTORS SPECIFIED WITH TYPE OF RESISTOR, TOLERANCE

AND RESISTANCE VALUE ARE "1/4".

3. ALL CAPACITORS ARE 50WV RATING UNLESS OTHERWISE NOTED.

5. THICK LINES ARE 15WATTS SUPPLY LINE.
6. VIEW OF TR & FET & IC.

7. ISOLATION BORDER LINE.
