All soldering should be CLEAN & NEAT! Trim excess lead lengths .. Now the two wire 

jumpers. 
 
13. 

Notice how there is a wire draped across each relay for each band ? This is the 

idea for our wire, Look below the RL1 spot (on the silk screening) and see "n ". This is 
where one end of wire #1 goes. Look above RL2, and see "n ". This is the other end. Just 
to the left of "n " is "g ". This is the one end of wire 2. Dress wire 2 neatly with the 
other wires in its path and connect the remaining end to "9 ". This final connection may 
be your hardest as there are some components and wires that have to be SLIGHTLY shifted 
to get access to the hole. This completes the jumper and wire section. 
 
NOTE: 

you may want to put your relays in first as wire 

1 goes over them.. this is your 

option. 
 
14. 

Now install the remainder of your components in the spots 

 

detailed in Fig 3, in the order listed. Remember to keep 

 

components flush to the board, leads snipped, and solder 

 cleanly 
 

1) 

RL1 & RL2 .. location is obvious 

 

2) 

Two jumpers (insulated) on foil side. (One of them may 

 

 

already be installed.)Use the other jumper component 

 

 

supplied cut leads off and use them as jumpers. Use the 

 

 

supplied insulation and solder these jumpers in the 

 

 

same manner as the other ones on the board. Neat & 

  Clean! 
 

3) 

L15 & L16 .. as per Fig 3. 

 

4) 

D1 diode, orientation on Fig 3. Cathode lead has white 

 

 

stripe. Bend cathode lead towards anode lead. Install 

 

 

anode lead into hole with white circle. 

 5) 

C1 

... 

68pf (cap says 68J) 

 6) 

C2 

... 

33pf ( cap says 33J ) 

 7) 

C2 

... 

100pf ( cap says 101J ) 

 8) 

C4 

... 

10pf ( cap says 10D ) 

 9) 

C5 

... 

82pf ( cap says 82J ) 

 
 

10) 

....... C38 .0047uf ( caps says 472 ) 

 

11) 

....... C39 .0047uf ( cap says 472 ) 

 

12) 

....... C10 82pf ( cap says 82J ) 

 

13) 

....... L1 LA141 (4 turns ) 

 

14) 

....... L2 LA142 ( 5 turns ) 

 
15. 

Is everything CLEAN ? Leads cut? Are you PROUD to say you performed this mod? If 

not, touch up your solder & clean it up till you are ! 
 
16. 

Double check your work, if all ok ( both sides ), re-install LPF cover plate ..  

( 3 screws )
