Stereo Jack lugs are

labeled Tip (T), Ring (R)

and (S) Sleeve.

Closed Circuit Jacks

have a Switch (X) in

place of the R lug.

This completes assembly of the 9710 circuit board. Admire your work for a few minutes
then take a break. When you come back, admire your work again but this time be critical. It
would be a good time to double check the orientation of polarized parts and that the right
resistors and capacitors are in the right places. Examine the solder joints. On the component
side make sure excess solder has not flowed though the hole. On the solder side, are they all
nice and shiny? If they have the "lumpy" granular look that indicates a cold joint, reheat them.
Solder bridges are less likely with a solder masked circuit board but they can still happen. If
you're not sure about a bridge refer to the foil patterns in fig 1.

Front Panel Controls

Now we will put the circuit board aside temporarily and mount the
controls, jacks and switch to the front panel. If you have the optional
FracRak accessory kit  you will be installing these parts at the
locations shown in fig 2.

Two kinds of jacks are used in the 9710; Closed Circuit Mono
(which have a built-in switch) and TRS (stereo). The differences
between these types are not apparent on casual inspection so
the two TRS jacks will be packed separately or otherwise indicated.

(  ) Using the nuts supplied with them mount the two 1/8"

TRS Jacks (J3, J6) at the locations shown in Fig 2.
Orient as shown in Fig 3 and hand-tighten the nuts.

(  ) Mount the 11 remaining jacks at the locations shown in fig 2.

Orient as shown in fig 3 before fully tightening the nuts on
all of the Jacks to secure them. Use only enough force to keep
the jack from rotating. Do not overtighten.
