[Elecraft] KPA1500 110v 240v

[RIchard Williams]

Do not fool yourself.  The Quadra is not a 1000W amp.  Try running 1000W out on  RTTY and see how long it lasts (if it will even approach that power without buenon up).
The amp is a 500W amp; it is rated at 1000 W PEP; that is a BIG difference than 1000W key down.  The new Elecraft amp is a true 1500W amp that will supply 1500 W out on RTTY.
Most 120V circuits in a house are not wired for a 35 Amp load.  Your Qudra pulls no where near 30 amps.  You can't work around W = I x E;  fill in the blanks.  Here is are the specs for a Alpha 9500 for 1500 W out:
Power: 100,120,200,220,240 VAC, 50/60 Hz, selection Automatic. At 240 VAC, requires 10 Amps per leg, for a total of 20 Amps.  Note: Although the amplifier will operate at 100V, the mains will have to be able to deliver upwards of 35 amps.

I am sure the new Elecraft amp is in the same ballpark.

without changing any wiring.  The power supply recognizes the AC mains
voltage and sets itself appropriately.  Why shouldn't all "modern"
amplifiers do that?
