Mount power adapter jack in 15/32" hole on bottom left side of box. Orient solder lugs on power
adapter jack so larger center-pin lug is facing the bottom side of box. Tighten adapter jack.

SECTION 3 – Connect the 5KL Potentiometer
Please refer to DRAWING 3.
Cut a 2" length of wire, strip ½" of insulation off of one end and
tin. Use this one end to connect the 5K pot lug #2 with lug #3.
Connect the other end of the wire to the ground lug of the input
jack.
Cut a 3" length of wire and connect the 5K pot lug #1 to the terminal
strip terminal #2.
SECTION 4 – Mount the Tube Socket, Shield and 5 Lug Terminal Strips
Please refer to DRAWING 4.
Use the #4 screws and nuts to mount the tube socket and shield as shown below.
1) From outside of the enclosure, insert the two #4 screws through the
mounting holes of the tube shield base and into the two 1/8" chassis holes.
2) Place the tube socket onto the two screws so that the gap between pins 1
and 9 is directed toward the end of the box with the footswitch.
Mount the socket with the large gap
between pins 1 and 9 on the side of the
enclosure closest to the footswitch.
Note: Due to variance in socket manufacturing, the pins on your socket may not be in the same position relative to the
socket's mounting holes as shown in the layout drawings; however, the gap in the socket will always be between pins 1
and 9. Make sure you are making your tube socket connections to the correct pin numbers with respect to the gap and
not their position relative to the mounting holes.
