Chapter 12. 10W PA Module

12

!

CAUTION

THE 10W PA IS, BASICALLY, AN OP-AMP
PROVIDING VERY HIGH GAIN WITH NEGATIVE
FEEDBACK. TRANSISTORS Q1 THROUGH Q5,
Q6, AND Q7 ARE THERMALLY CONNECTED,
I.E., THEY ARE MOUNTED ON THE SAME PART
OF THE HEAT SINK. ANY FAILING TRANSISTOR
MAY AFFECT OTHER TRANSISTORS. CHECK
EACH TRANSISTOR SEPARATELY. IF NO
FAULTS ARE FOUND, CHECK OTHER COMPO-
NENTS.

BE CAREFUL

NOT TO MISPLACE THE

SCREWS, SPRING WASHER OR INSULATING
WASHER USED TO MOUNT Q1 THROUGH Q8.
DAMAGED SCREWS OR INSULATORS SHOULD
NOT BE USED.
