[sdiy] IN400X diodes (was: 1N914 vs. 1N4148)

[harrybissell]

The higher voltage diodes are almost certain to have a little more forward
drop at a given current... and higher junction capacitance.

Then again... who would notice, or care ???

(if as Paul says, they ARE the same, then they will have pretty much the same
drop and capacitance...  :^)
