It is not a particularly full replacement, just two soldering irons with dimmers and a voltage display.
For a long time they wanted to collect such a stray in garage.
Actually, everything is simple. The case is from a computer power supply, two switches, two voltmeters, two dimmers with external variable resistors (potentiometers) and two sockets.
Dimmers are not Chinese, they took from "Master KIT". The sockets were specially taken of the old model, so that by chance people would not stick Euro plugs there and try to regulate drills and other electric heresy)))
Dimmers are not very powerful, 500 or 800 watts, I do not remember exactly.
