Section Two – Amplifier Module Construction
Circuit Board ID is HFPA-2013 V 4 R5
Circuit Board Assembly, HFPA V5
Assembly Steps
•
Install 0.1 uF capacitors (104): C22, C4, C1, C9, C2,
C6, C8, C3, C7, C23 Install
•
Install 47 pF (470J): C5
•
Install 0.01 uF capacitors (103): C11, C10, C12
•
Install 1000 pF capacitor (102): C13 Install
•
Install 1 uF capacitor (105): C17. The long lead is (+)
and goes in square pad marked (+)
•
Insert 1N4007 diode at D2 (smaller of two axial
components with cathode stripe at one end). Bend
leads very close to the body to match the component
outline on the board. Make sure cathode bar on the
part matches the cathode symbol on the silk screen
outline. Install
•
Insert RL251 diode at D5. The leads are bent
approximately 1/8 inch away from the body to fit the
component outline on the board. Make sure cathode
bar on the part matches the cathode symbol on the silk
screen outline. Install
•
Install six 1K 1/8W resistors (BRN BLK RED): R14,
R20, R15, R10, R21 and R12. Install
•
Insert two 4.7K 1/8W resistors (YEL VIO RED): R17,
R19. Install
•
Insert two 27 ohm ½ w resistors (RED VIO BLK):
R1,R2 Install
•
Insert three 10K 1/8w resistor (BRN BLK ORN): R5,R6
and R4 Install
(R5 partial symbol on board)
•
Insert one 27K 1/8w resistor (RED VIO ORN): R13.
Install
•
Insert one 3K 1/4W resistor (ORN BLK RED): R18.
Install
•
Insert two 1.2K 1/8W resistor (BRN RED RED): R16,
R22. Install
•
Insert one 1M 1/8w resistor (BRN BLK GRN): R11
Install
Note:
if you did not purchase the PINET 100-PI Option Module,
install R3, R7 and R8 next. Otherwise wait until instructed to install
alternate values for R3, R7 and R8 in the 100-PI section.
•
Insert two 100 ohm 2W resistors at R7 and R8. Install
•
Insert one 62 ohm 2W resistor at R3. Install
