Preliminary Wiring of V1 Tube Socket
Step 1
– Cut three short 1” lengths of 20AWG buss wire.
Step 2
– Slide a 1/2” length of salvaged insulation over each of these wires
(photo 5.16a).
Step 3
– Tack solder the first wire jumper in place between pins 2 and 7.
Step 4
– Tack solder the second wire jumper in place between pins 1 and 6.
Step 5
– Tack solder the third wire jumper in place between pins 3 and 8.
Installing the Rear Plate, Fuse Holder, and 1/4” Jacks
Step 1
– Remove the thin tape cover to expose the double stick tape on the back of the rear
plexiglass panel of the back plate.
Step 2
– Install this rear plexiglass panel on the back of the chassis, being careful to center
all the holes correctly before pressing firmly.
Step 3
– Install the two Cliff mono 1/4” jacks (with chrome nuts) into the speaker output jacks
with solder terminals facing up for easy soldering.
Step 4
– Install the fuse holder. Insure the middle terminal of the fuse
holder is facing up for easy soldering.
Step 5
– Install the stereo footswitch 1/4” jack (all plastic) through the
chassis and faceplate with the terminals facing up.
Installing the Impedance Selector
Step 1
– Enlarge the speaker selector switch mounting hole in the rear plate by drilling a
7/16” hole in place of the present hole through both the rear plexiglass plate and chassis.
Step 2
– Deburr the plexiglass and metal chassis and insert the impedance selector switch.
Step 3
– Align the selector switch with the common solder terminal facing up (photo 5.18a).
Installing the AC Entry Receptacle
Step 1
– Hold the AC entry receptacle so that the middle prong solder contact will be clearly
visible when installed into the amp.
Step 2
– Press The AC entry receptacle firmly into the square cut out in the rear plate and
chassis until it “snaps” into place.

For a great final tone control, the “Tone Cut” mod can be mounted in one of the speaker
jack chassis holes at this time. Refer to “Cool Modifications”, Chapter 11 for more
information.

WARNING
During all drilling and cutting operations, it is important to wear
proper eye protection and follow appropriate safety rules.
NOTE
The assembly video shows installing a different type of AC entry receptacle. These snap-in
types are easier to use and the solder contacts are larger.
