Build directions
This design is quite easy to build and the building order is not critical but since you have high and low parts tight together it could be a good idea to start with the low parts first.
Suggested building order
- Resistors
- Diodes
- Polyester caps
- Rectifier bridges
- Small electrolytic caps
- Varistor
- Fuse holder
- LM317 and LM337
- Wago terminal blocks
- Big caps
- Transformers

Each halves are isolated from each other and the way to tie them together is to solder the ground planes together, all the way or just a part. It should be better to do is I have done in the picture but it won't hurt I'll guess to solder all the way.
Build two positive regulators
- Do not mount LM337, IC2
- Mount IC3 with a LM317
- Change direction for all diodes
- Change direction for all electrolytic caps
- Change direction for the rectifier bridge
