Series Diode in Power Supply Line #ubitx

Rob French (KC4UPR)
 

Hey all, I'm planning on putting a couple of diodes in series with the positive line from the power connector, to bring down the voltage a tad.  Just wanting to make sure I'm not missing something... If I do that, do I still need the reverse diode from the negative to positive terminals?  I would think that the series diode in the positive supply line would be sufficient.  

Thanks!
