Insulated vario trafo, with current limiter

I tried to modify the peevishly mentioned variao solution, and added a DC outbut. Then I found an almost finished solution, I modified with an "old fashioned" current limiter, using incandescent bulbs in series with the load.

With some on-off-on Rocker switches, made me able to select the limiter to 30W, 60W, 90W and 120W.

The current is by sitting in series with an incandescent bulb, it works as a current limiter resistor ( U / R = I ), simple ohms law, and if there is a short, in the tested device, the bulb will light up, or if the current limit is getting closer. I use 60W bulbs as shown in the diagram.

Again, I had issue, adding the DC output, on the front panel, it looks like I have room, but the insolation transformer is placed at that location. And I was not able to find a matching voltage meter. Now there is an AC voltage meter, a mA ammeter for when the current limiter is selected, and a normal ammeter, for when the current limiter is overridden.

The protective earth wire is wired through a switch, to being able to select letting the protective ground to the socket, or being able to insulate the protective ground.
