F5 Turbo Assembly Instruction Version 2 Page 2
3. Assembly Instruction:
a. Solder the ¼W resistors per BOM. Note that a gap about 1mm should be allowed between
the body of resistors to the top of PCB. This is to prevent any arcing of high voltage from
resistors to the ground plan.
b. Solder the 8 pcs film capacitors, 2 pcs LEDs, and 3 VRs. Note that the VRs P1 and P2 should
have the same direction of the P3 as shown below.
c. Solder the 3W resistors.
d. Solder the Jfets K170 and J74 (Q1 and Q2). Then solder the transistors Q7 and Q8.
e. Lastly solder the E-capacitors.
f. Note that J15 and J16 (TH1) are varistor 4k7 (black color). The leads should be insulated by
the shrink wrap provided.
g. J6, J8, J10, & J11 are M3 holes mounting for the PCB. Use a M3 x 16mm with 10mm post
(bottom side) to mount the pcb onto the heat sink.
h. Q3, Q4 and Q9 are marked IRF9240, solder 2SJ201 at these locations.
i. Q5, Q6, and Q11 are marked IRF240, solder 2SK1530 at these locations.
