Interesting how my original comment specifically about powering the PR6 and the P3 generated such a wide spectrum of (dare I say irrelevant?) responses!
First, I agree that an RCA "y" is a reasonable fix. I don't happen to have a RS store close by, and to order a "y" seems unreasonable, at least until I have some other items to add...I can get along without the PR6 until then...when 6 is open, attenuators are more in demand than preamps...in the day-long opening on 4/27 I ran almost all day with the attenuator "in." Second, I don't plan to plug in the coffee pot or an electric blanket, just the PAR6 and P3. I do not like the idea of adding yet another little box to the collection I already have, to accommodate a 12 volt relay and jacks. If I wanted to do this, I would just connect the PR6 to the K3's power supply directly, as it is usually "on" when the K3 is on. Third, it might be just as easy to drill a hole and mount another RCA (or whatever) jack. The reason to NOT do this turns on whether Elecraft would touch one of their units that has been "violated." I recently had a very negative interaction with TenTec who refused to repair one of their boxes because it had an extra power outlet installed in the back apron..."custom modification, yatadda yatadda..." I have nothing against coffee pots. John Ragle -- W1ZI ===== On 5/3/2011 9:41 PM, Fred Townsend wrote: > I would disagree on being the 'most reasonable' [fix].
