[Elecraft] P3 with SVGA

Hi Don.

Thanks for the info.

I performed the 1 Amp mod on my K3 myself, so I'm quite sure it's 1A capable 
and yes it does have the 1A label.

I'll look for a quality adapter. As they're normally meant for audio work, I 
was a little concerned that the internal wiring might only be intended to 
carry milliamps.

73,

Alan,

Look at the label on your K3 12 volt output jack.  Does it say 0.5 amp
or does it say 1.0 amp?  The 12v change includes a sticker to re-label
the jack.

Yes, you could use a "Y" adapter, but use a good quality one so you
don't have a significant voltage drop due to loosely fitting connectors.
