Added Heat Sink with 2 additional diodes inside the case to
handle the in rush of current when you turn the supply on. 
Now instead of two diodes handling all the power. There are
four diodes that handle this power.

Stock 2 diodes that come with the 50M power supply.

Over Voltage protection board that was added.

The transformer on a 50M  is the same as a 60M, the only difference
from this supply and the  60M  is an extra capacitor and a fan.
