Introduction
This is the build guide for the Amp Camp Amp
v1.6.
The differences between the 1.5 and 1.6 are fairly minor - the circuit is identical to the previous version, all the parts other than some chassis
mounted components are the same. The schematic is the same, and part numbers are the same. The biggest changes are a different layout of
the PCB, inclusion a front mount power switch, and the rear switch is now used for RCA input stereo/mono.
Please note that
the wire colors have changed in batch 3.
While some colors are unchanged, there are now more unique color pairs, and we
have updated the wiring diagrams with the new colors, however the photos and videos in the guide have not yet been updated. Please print
out the correct wiring diagram to match your batch (steps 33 and 34), and refer to it while you build.
If you have any comments or tips on any step please leave a comment.

Step 1
Print the schematic
Print this out on paper and have it in front of you
during the whole process.

Step 2
Prepare to stuff the boards
The various components are all found in individual
bags as shown.

Step 3
Parts overview
In the various bags of the kits you will find
hardware,
The XLR jack,
The transistors and LEDs.
The big transistors are the Mosfets (Q1 Q2), The
smaller of the two other transistors is the ZTX450
(Q3), and the slightly bigger one is the input Jfet
(Q4)

Step 4
Speaker posts
Speaker posts.
Try the washers in the posts as shown, some posts
will fit the small washer flush on this side, some will
fit the shoulder washer on this side.
It doesn't matter if the shoulder comes first or the
other plastic washer, as long as things sit squarely
and the shoulder washer is inserted through the
chassis so the threaded portion doesn't touch the
back panel itself.

Step 5
Stuffing the PCBs
Now we will stuff and solder the components onto
the PCB.
Get the resistors and capacitors, and place the
keratherm insulators aside for the moment.
Image 3 shows the two properly stuffed PCB,
assisted by the fact that the schematic was printed
out and referred to during the whole process. :) :) :)

Step 6
Measure ALL the parts first
Measure EVERY RESISTOR before placing in the
board :)
Panasonic power resistors: It's difficult to measure
these because the resistance of your multimeter
leads (normally 0.2-0.4Ω) will be added. You can
measure your leads and subtract the value, just
trust the values which are printed on them, or
build
a low resistance value test rig.
Have the schematic printed in front of you at all
times. The schematic marked 1.1
is correct
for the
1.6
The resistor tape is marked in a way shown on the
documentation in the box.
Measure everything
regardless.

Step 7
Stuff the resistors
Generally it's easiest to start stuffing the PCBs with
the smallest components first - in this case the
resistors.
Note the 1% resistors all have a brown band at one
end - to help assist troubleshooting in the future if
needed, place the brown at the
bottom
of all
resistors.
Slightly bend out leads before soldering
