Power Supply Running to hot

Hey if i was to try this would I use standard rectification diodes or zener or would both work because they both give a voltage drop. Of course properly rated

All of the above will work, even Schottky diodes will be OK. Of course you have to calculate based on the forward drops of your chosen diodes; a 0.7V silicon diode will dissipate 0.7W at 1A (nice and warm but fine), but a 5V zener will dissipate 5W at 1A (smoke).

could i use some 1n4004

What's the supply current? Try doing the calculation yourself, and we'll check for you.
