I've seen the postings about providing power from the K3 Aux 12v socket - is
there enough to drive the 6m Pre-amp and the P3?

Don't say you don't have enough time. You have exactly the same number of
hours per day that were given to Helen Keller, Pasteur,
Yes. The 12 V aux current should be kept below 500 mA, and the P3+PR6
should be well below this.

I would think we users are getting to a point where a good, automotive relay
designed for continuous duty usage would be a good idea here. Simply use
the 12v auxilliary power to feed the coil of the relay and let the contacts
of the relay feed power from our 12v supplies. I don't remember the
Thanks Wayne - just need to make a 'Y' lead now :-)

For that application even Radio Shack has 2. Numbers 275-226 275-218.
My local NAPA store also had them in blister packs but I have not
checked in awhile.
They were a little more in cost than Radio Shack.
A relay in this usage is a mechanical current amplifier.

I went to radio shack and got the relay I needed. I then built a box
that will pass 10A to several RCA connectors (I wanted to be able to
plug the units plugged into the box into the K3 when portable with a sub
set of my goodies). Anyway I then also got a few of the cheapy cores

I've answered my own question ...
No, the three units add up to about 1.2A ... Far too
much current for the 12VDC OUT jack to support.
