Not my best soldering, I had to adjust the components a few times so it's kinda messy, works fine tho.
This is the swich on the front panel, I may change it for a less conspicuous one.
Here you can see the regulator I used.
-IEC type connector with fuse holder as power input.
-SPST toggle switch
-transformer, 2x9V I forgot the current rating. Wired in parallel.
-LM2940T-9.0 LDO regulator, this is like a 7809 but with just 0,5 voltage drop.
-2x 100n ceramic capacitors for decoupling.
-4x 1N5819 diodes for the diode bridge.
