The kit consists of PCB, Panel, bags of components and knobs.

Step 1
Solder TH polarized capacitors, trimmers and J201 transistor.
C4: 4.7uF, C5: 100uF, C1: 1uF.
Pay attention to the orientation of the transistor and capacitors.

Step 2
Solder all the pins. This step is (optional). Otherwise, you can solder
wires directly. However, I strongly recommend using pins.

Step 3
Remove the anti-rotational tag using wire cutter.

Step 4
Secure banana jacks, push button and switch on the front panel.

Step 5
(identical to through-hole version)
Position potentiometers, switches and standoffs. Don’t solder yet.
Secure them to the front panel, and tighten. Solder AFTER tightening.

Step 6
(identical to through-hole version)
Cut and strip the wires. Pay attention that the colors of wires can be
different than you see on photos. First, wire the switch. Connect the
pins on the PCB to the pins on switch according to the photo.

Step 7
(identical to through-hole version)
Now wire the button. Connect the pins on the PCB to the pins on
button according to the letters – A B C.

Step 8
(identical to through-hole version)
Wire the banana jacks.

Step 9
It’s a good time to verify all the wiring you have done. If everything is
good – move to the last step.

Step 10
Now you can put the knobs on. Congratulations!
