Connect the ¼” inner conductor end to the 500KL pot’s “wiper” lug.
Connect the ½” shield conductor from this same wire end to the 500KL pot’s “cold” lug.
Connect the other end of this wire to V3 pin 7.

Connect the ¼” inner conductor end to T10(1).
Connect the ½” shield conductor from this same wire end to T10(2).
Connect the other end of this wire to the input jack’s tip lug.
Check for shorts in the shielded wire:
Make sure the shield in not accidentally shorting out the inner conductor of the shielded wire by taking
resistance measurements with an ohm meter. If the wire is shorted, the signal will be grounded out.
Measure resistance between T10(2) and the 500KL pot’s “wiper” lug. With this pot turned all the way
down, you should measure about 0 ohms. (You might actually measure 2 or 3 ohms, but that’s close
enough to zero). With the pot turned all the way up, you should measure about 500KΩ).
If you measured close to 0Ω with the 500KL pot turned all the way up, the wire has a short and you will
need to prepare a new shielded wire being careful not to overheat the shielding or inner conductor so that
the insulation is compromised.
Measure resistance between T10(1) and T10(2). You should measure an open circuit (or resistance that is
too high for your ohm meter to measure, infinite resistance).
If you measured close to 0Ω, the wire has a short and you will need to prepare a new shielded wire being
careful not to overheat the shielding or inner conductor so that the insulation is compromised.

Tip: Some people may like to add insulation over the shielded end that has
been cut away to prevent the possibility of having an accidental short.
Consider adding heat shrink or corona dope to this
area for added insulation between the shield and
inner conductor.
