[Elecraft] Another really good reason to come to the Visailia DX convention this weekend...

[Dauer, Edward]

It might, but at typical efficiencies 1500W peak output would be a significant draw on the existing 117 VAC wiring – likely over 20 amps.  With the K3/KPA500 as it is I get a just perceptible flicker in the room lights when keying.  With a dedicated 240 volt line I could also add a cooler for the drinks.

    Not so fast on the 240 VAC line Ted.  The single transistor SPE 1.3K will do 
    1500 watts on 110v. It will be interesting to see if the Elecraft 1500w AMP 
    turns out to be a single transistor design...

    Guess I have to get an electrician to come out and give me another quote on 
    a dedicated 240 VAC line to the shack.
    
    And all new baluns.
    
    And I have to check if the remote antenna switch relays are rated for more 
    than 600 watts; if not, then replace that.
    
    Several hundreds of feet of coax to replace all of the ’58, right?
    
    Ferrite chokes and bypass caps on the external lighting around the house, 
    and on the outside motion detectors.
    
    Anything I’ve left out?
