Went together easy. Worked!!! What more could you ask for! Keep in mind that you need a 12v AC power source for this pre-amp.

4.0 out of 5 stars Higher quality than most other kits I’ve played with

Pcb is labeled exceptionally well, almost done assembling and had no issues at all with the fact that no documentation comes with this kit. The only problem is that all the large electrolytic capacitors were the wrong values from what is actually printed on the PCB... we will soon find out if it makes a difference :/
