2. Desolder the other end of this wire from the center terminal of the treble pot. The
right channel treble pot is closest to the front panel of the preamp.
3. Similarly, desolder the wire that connects to the LEFT channel circuit board
eyelet 17. The left channel circuit board is closest to the back of the preamp. Use
the toothpick to clear the hole as described above.
4. Desolder the other end of this wire from the center terminal of the left channel
portion of the treble pot. The left channel portion of the treble pot is closest to the
back panel of the preamp.
5. Identify the red and black pair of wires which in Figure 5 are identified as
TREBLE CENTER and 17 in the upper left half of the Figure.
a. Route the black wire of the pair to eyelet 17 of the right channel PCB
(closest to the front of the preamp). Cut it to a comfortable length, strip off
¼" of insulation, insert it through eyelet 17, and solder it on the solder side
of the board.
b. Route the red wire of the pair to the open center terminal of the portion of
the treble pot closest to the front panel. Remove ¼" of insulation, and
solder the wire to the middle terminal of the pot.
6. Identify the green and black pair of wires which in Figure 5 are identified as
TREBLE CENTER and 17 in the lower left half of the Figure.
a. Route the black wire of the pair to eyelet 17 of the left channel PCB
(closest to the back of the preamp). Cut it to a comfortable length, strip off
¼" of insulation, insert it through eyelet 17, and solder it on the solder side
of the board.
b. Route the green wire of the pair to the open center terminal of the portion
of the treble pot closest to the back panel. Remove ¼" of insulation, and
solder the wire to the middle terminal of the pot.
7. Identify the red-black-red trio of wires that connect to the upper right half of the
switch as shown in Figure 5. Form the trio over towards the bass pot, the group of
terminals that connect to the front section of the bass pot.
a. Connect one of the red wires to an outside terminal. This will be in
addition to the wire already in place that connects the pot to a PC board.
b. Connect the second red wire to the other outside terminal of the front
section of the POT. It doesn't matter which red wire goes to which outside
terminal. (there is already a wire on this terminal also).
c. Connect the black wire to the center terminal of the front section of the
bass pot, joining the wire that is already there.
8. Identify the green-black-green trio of wires that connect to the lower right half of
the switch as shown in Figure 5. Form the trio over towards the bass pot, the
group of terminals that connect to the rear section of the bass pot.
a. Connect one of the green wires to an outside terminal. This will be in
addition to the wire already in place that connects the pot to a PC board.
b. Connect the second green wire to the other outside terminal of the front
section of the POT. It doesn't matter which green wire goes to which
outside terminal. (there is already a wire on this terminal also).
c. Connect the black wire to the center terminal of the rear section of the bass
pot, joining the wire that is already there.
