Thanks to being licensed we know:
P = U * I
so
120V * 15A = 1,800W
240V * 10A = 2,400W
We remember that legal limit is 1,500W, although the LA-1K should only be run up to 1,000W.
Some power goes out in heat.? Maybe 200W? [shrug]
In the manual the specifications states: "AC POWER 100-125VAC @ 15A or 200-250VAC @ 10A".
With all this information, that you as a technician operator have, you can be assured that a 15A circuit on 120V is fine.? The trouble is we extras have taken the technician exam so long ago we forgot the basic formulas.
The mysterious 33A is in a section of the manual where also the LA-1K 50V Vd is mentioned.? Hey, since we are technician we quickly realize that 50V * 33A = 1,650W.? This section is talking about the amplifier shutting down when this current exceeds 33A (i.e. we're taking the amp to it's limit). It seems reasonable when maxing out the amp that 1,000W (or more) goes to RF and a hole bunch of additional power is used to generate heat.? We can conclude that this is not the current on your outlet!? I do agree this section is not written clearly and can be confusing at first.
