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.
