Important Safety Notes
By purchasing, using, or assembling this kit, you have agreed to hold Akitika LLC
harmless for any injuries you may receive in its assembly and/or use. To prevent injuries:
Wear safety glasses when soldering or clipping wires to prevent eye injuries.
Always unplug the power before working on the amplifier.
Large capacitors hold lots of energy for a long time. Before you put your hands
into the amplifier:
o
Pull the AC plug!
o
Wait 2 full minutes for the capacitors to discharge!
Remove jewelry and rings from your hands and wrists, or anything that might
dangle into the amplifier.
If working one the equipment with the power on, keep one hand in your pocket,
especially if you’re near the power supply or power supply wires. This can
prevent serious shocks.
Build with a buddy nearby. If you’ve ignored all the previous advice, they can
dial 911 or get you to the hospital.
Read and understand the safety manuals of all the tools you use.
