[Elecraft] Power supply diode voltage question

[G8IFF/KC8NHF]

A 1N5400 series would be OK for a barefoot K2. A 1N4000 series isn't big 
enough.
If you just need to reduce voltage why not open up the power supply and 
look for a voltage setting pot?

I'd planned to install a diode in series with the+ve of the PSU, and just wanted to check which diode I should use ? I have a supply of 1n4004's which I think will give me the required voltage drop, but just want to check that these are OK (I note they are rated at 1A, and think I might need something bigger ?).
