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.
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.
4. PARTS MARKED WITH
5. THICK LINES ARE 15WATTS SUPPLY LINE.
